Exogrid: someday you'll be mine

 

Beauty is More Than Skin Deep.

The patented Exogrid Technology adds another dimension to the already proven performance of the Racer X. The multi-material makeup of the frame’s down tube works to absorb the small washboard bumps encountered at high speed that the suspension can’t respond to. When you combine the lightweight downtube with the most efficient rear suspension platform in cross country today, the end result is a thing of beauty.

Rider-centric custom geometry is available on all Exogrid and titanium frames. Hand-crafted in Tempe, Arizona all of our Exogrid and titanium frames are available with custom geometry. The perfect fit of man and machine is easily achieved through our extremely simple Custom Fit Program.

Features:

• Seamless 3Al/2.5V titanium front triangle featuring a patented, Exogrid downtube
• Hand-crafted in Tempe, Arizona
• Custom tuned Fox RP23 provides100mm of rear wheel travel
• Precision machined 6Al/4V titanium shock tabs
• Triple, oversize, sealed-bearing main pivot
• Compression molded, multi-direction carbon fiber X-Link
• Hydro-formed chain-stay
• Clevis Style Horst Link pivots captures each dropout eliminating independent dropout flex
• Carbon seat-stay
• Sizes: XS, S, M, L, XL, Custom

 

Next Generation Full Suspension

Just like any cutting edge industry, the top players eventually reach a point where the products in the market place that the customers can choose from are all generally good. It happens with cars, motorcycles, computers, and now full suspension mountain bikes. Sure, there's still plenty of basic single pivot bikes and a few other generally outdated designs out there, but the top performers in the suspension world have basically adopted three types of designs. Please keep in mind that not all bikes are created equal. As with almost anything you can buy, just because a company touts a cutting edge design does not mean they are automatically cutting edge or high quality for that matter. A Hyundai may use a similar suspension design to a BMW, but that does not make them a top performer (sorry Hyundai). We believe that there are plenty of "good" bikes out there, but there are only a few truly great ones. So how do you know what the best suspension design out there is? How do you know what to buy? Read on and I'll tell you at the end.

FLOATING BOTTOM BRACKET DESIGNS
Floating Bottom Bracket shell designs were developed by GT Bicycles for use in their I-Drive system. This design as well as similar ones used by Maverick and Klein, place the entire bottom bracket and crank assembly as a floating pivot between the front and rear triangle of the bike. This differs from most full suspension bike designs, where the bottom bracket is part of the bikes front triangle, or in the case of a unified rear triangle design, the bottom bracket is part of the rear triangle assembly. Floating bottom bracket designs can exhibit most of the great characteristics attributed to full-active 4-bar link style designs in that they can be designed to resist pedal bob and the suspension can remain active under braking (i.e.: it does not lock the suspension out, stiffen it up, or raise the rear end of the bike as the rear brake is applied) Overall, this suspension system has always had potential. However, current designs on the market are not perfect. The current I-drive configuration, although lighter then the previous generation, is still fairly complex and has not changed enough to take true advantage of stable platform shock technology. The Maverick/Klein style floating bottom bracket design is straight forward, and relatively simple. However, the design is tied to a special front derailleur and a very custom rear shock which cannot be switched out for different brands of shocks as technology moves forward. Also, the design's very slack seat tube angle makes it difficult for some riders to attain the correct positioning over the pedals and there are some front derailleur shifting issues that seem to plague the current design.

Bottom Line
Floating Bottom Bracket designs have potential but still need some additional fine tuning to achieve the level of refinement available from some of the other fully active suspension designs on the market today.

Companies that feature these designs
I-drive: GT, Schwinn, Mongoose. Other Variations: Maverick, Klein, Seven

VIRTUAL PIVOT DESIGNS
Bikes referred to as Virtual Pivot Designs feature a double linkage that connects the front and rear triangle of the frame. This differs from a fully-active 4-bar link style bikes which use one pivot between the front triangle and lower swing arm with a single linkage up top to activate the shock. With virtual pivot designs, the attachment points of the two separate linkages from the front and rear triangle plus the length of each linkage will decide the overall path that the rear triangle moves through space. This path is infinitely tunable and is not restricted to a specific straight line or arc. The rear end of the bike can pivot in virtually any path determined by the designer. Because the main pivot point is always moving depending on where the rear suspension sits in its travel, an exact main pivot location does not actually exist, hence the name "Virtual Pivot".

When most people think "Virtual Pivot", they think of the VPP bikes by Santa Cruz and Intense. These bikes use a specific type of Virtual Pivot design that was originally developed and patented by Outland Bicycles about 10 years ago. The patents cover a specific linkage configuration and rear wheel travel path that is designed to aid the pedaling performance of a rear suspension bike without negatively affecting the overall bump absorption capabilities of the suspension. VPP bikes feature an "S" shaped rear wheel path. As the suspension moves through its travel, it does not swing a standard arc or move in a vertical wheel travel path. The path is similar to a stretched out or elongated "S". In addition, as the two linkages guide the rear wheel through this path, they reach a point about 25-30% into the suspensions travel where the two linkages oppose each other and form what can be best described as a very light lock-out or stopping point in the suspension travel. This point typically coincides with the amount of sag (the amount the suspension settles from your body weight) that you would run on a rear suspension bike. It takes very little bump force to move the linkages past their opposing point. The result is a bike that pedals well at the "sag" point yet is still relatively free to pick up bumps. So what's the downside? The double link design on any virtual pivot design adds a lot of complexity to the frame, and small linkages are forced to handle the majority of the frame loads, so frame stiffness and durability suffer in order to keep the weight down, or in the case of down hill designs, the frames become very heavy. Also, having a link behind the cranks severely restricts tire clearance making lighter, cross-country based virtual pivot designs with short chain stays almost un-rideable in muddy conditions. From a ride standpoint, the bikes pedal well when at the sag point but will still oscillate or bob on fire road type climbs or under hard sprinting. VPP designs still benefit heavily from stable platform shock technology to aid pedaling at other points in the suspension travel. Some riders contend that the bikes lack the lively accelerative feel of some other designs and don't maintain traction as well on climbs as some of the designs on the market. Finally, like single pivot bikes, VPP bikes suffer from brake jack, which is a stiffening of the suspension as the rear brake is applied, resulting in reduced bump absorption or potentially locked out suspension under hard braking. This is a problem that does not plague fully-active 4-bar designs.

What about other "Virtual Pivot" designs? Because the designer is free to send the rear wheel in whatever path, he/she desires, the possibilities are endless. However, there is no getting around the amount of moving parts, and overall complexity of any virtual pivot type design.

Bottom Line
"Virtual Pivot" designs are generally good 3rd generation suspension designs. Pedaling performance is an improvement over most single pivot designs. However, the complexity, frame stiffness vs. weight, tire clearance and overall chassis feel still leave them a step behind some of the more cutting edge fully active designs today.

Companies that feature virtual pivot designs
Santa Cruz, Iron Horse, Ibis, and Giant

4 BAR LINKAGE DESIGNS: AKA HORST LINK
There's never been a more hotly contested suspension design on the market than the 4-Bar linkage design with the Horst Link. This design has been around only slightly longer then the original Outland VPP, but its instant success and many attributes have made it the most valued and fought over suspension design in the world. The original design was developed by Horst Leitner at AMP research. The driving goal behind the design was to isolate braking forces from affecting the suspension performance. The first generation Horst bikes did not stiffen up or lift (brake jack) under hard braking. They were and still are to this day "fully active". The icing on the cake was that the original bikes pedaled better than anything else at the time.

The original Horst patents were purchased by Specialized Bicycles and are selectively licensed to only a few companies in the USA. In Europe and Canada where the US patents don't apply, Horst Link style bikes are the dominant suspension design. Just like with virtual pivots, and floating bottom bracket designs, many of today's 4 bar designs are at least 3 generations beyond the original. Everything has been changed to make the already great pedaling design even better without affecting the bike's excellent performance under braking. Four bar bikes, are light, strong and can be built extremely stiff without the complexity and issues associated with other suspension designs, plus they don't stiffen up under braking. If you own a suspension bike, you want the suspension to work. One of the worst traits a suspension bike can exhibit is to have the shock get progressively more locked out as you are braking hard into a bump filled corner. This is when you need the suspension most and this is just one of the areas where the 4 bar delivers and others can't.

So what's the downside? There is almost nothing bad that can be said about a well made 4-bar design. However, nothing is perfect. Because of the way the suspension works, long travel 4 bar bikes frequently need to have an interrupted seat tube design to the front triangle. Although there is no performance or handling downside to this, some riders prefer the traditional look of a standard front triangle and/or like to have the wider range of seat post adjustment of non-interrupted seat tube bikes.

Bottom Line
Current 4-bar designs from high end companies have the edge over anything else on the market. The ability to build light, class leading bikes at any travel range with ample tire clearance, great pedaling feel, in a fully active chassis with the highest level of durability is a combination that cannot currently be matched by any of the competing designs on the market.

So, are we a little biased? Of course we are, but that's ok because it's our article and there's no real need to be politically correct. The reality is that all the above designs are excellent. If you read closely, all references to the downsides of any particular design said "currently". That's not to say that any of these and maybe some new ones will be better. Maybe they will tackle the short comings of the current designs. With every generation, every model year, etc., we all continue to get better. Our competitors are working just as hard as we are to make sure their latest performs better then the last and we continue to develop products to stay ahead of our competitors. It's a game that never ends. But right now, I can say with the utmost confidence, that the ride, performance, durability, and just about any other measurable aspect of a Titus bike is better then our competition because it is not just the suspension design, and it is certainly not the marketing or the hype. It's about the details, and Titus does the details better then anyone. It's not just a pretty paint job, but a perfectly designed main pivot, the right size tubing to optimize lateral stiffness, and a partnership with the shock manufacturers to give us what we want and to not just accept what they have to offer. These are just some of the details that make a Titus a Titus. Yes, we just happen to build the most kick ass 4 bar, Horst link bikes, in the world, but it wouldn't matter if we were building virtual pivot or floating BB designs either. They would still be great and they would still be better because we sweat the details to make it the best bikes in the world and being better is what makes a Titus the bike to have in the past, present and well into the future. So, if you don't already own a Titus, you have no idea what you're missing and if you do, tell them what they are missing. In the mean time, keep on riding and we hope to see you out on the trail.

Forks

Sizing

Do I need a 1” or 1 1/8” fork?

You can measure the diameter of the steerer tube of your current fork, which comes down out of your frame where your fork blades meet above the wheel. This is the part that runs up into your head tube. Most mountain bikes require 1 1/8". To be sure, simply measure the diameter of the tube, the distance from one side of the outside wall of the tube to the other.

What else do I need to know to determine fork compatibility for my bike?

Older forks are usually threaded. If your bike is newer, it may be outfitted with a threadless style fork. If this is the case, you need only worry about the diameter of the steerer tube (1-, 1 1/8, 1 ¼ or 1 ½ -inch). You can measure this by loosening and removing your stem from the fork and measuring the outer diameter of the steerer directly. Threadless forks need to use a threadless headset and stem. Threaded forks use a threaded headset and a stem with a quill.

In a threadless system the fork's steerer tube will pass through the head tube of your bike and the stem will clamp on to the portion of the steerer tube that rises above the headset. In a threaded system the fork's steerer tube goes into the head tube but does not pass through the top of your headset. In this system the stem (somewhat "L" shaped) inserts directly into the headset and fork's steerer tube.

The two systems are not compatible and you must use a threadless stem with a threadless fork, and a threaded stem with a threaded fork.

Threadless forks generally come with a steerer tube that is a standard length and must be cut once you determine the proper length for your bike.

Will I need any other parts to install my new fork?

All the new forks are set up for V-brakes and do not have a cable hanger on the brake arch. Since cantilever style brakes will not work without the cable hanger on the brake arc, you may need to upgrade to V-brakes (note you will also need to get V-brake levers). As long as you ordered the correct size fork, everything else should transfer over.

Threaded vs. Threadless

Is my fork threaded or threadless?

In a threadless system the fork's steerer tube will pass through the head tube of your bike and the stem will clamp on to the portion of the steerer tube that rises above the headset. In a threaded system the fork's steerer tube goes into the head tube but does not pass through the top of your headset. In this system the stem (somewhat "L" shaped) inserts directly into the headset and fork's steerer tube.

If your stem is threadless so is your fork. Older forks are usually threaded. If your bike is newer, it may be outfitted with a threadless style fork. If this is the case, you need only worry about the diameter of the steerer tube (1-, 1 1/8, 1 ¼, 1 ½ -inch). You can measure this by loosening and removing your stem from the fork and measuring the outer diameter of the steerer directly. Threadless forks need to use a threadless headset and stem. Threaded forks use a threaded headset and a stem with a quill.

Do you sell threaded forks?

No, all our forks are threadless. You can easily convert your bike to threadless by installing a new headset and new stem. Then you can get a threadless fork.


Travel/Damping

Would a long-travel fork or a short-travel fork be best for me?

It all depends on the kind of riding you do. Generally, long-travel forks are designed for downhilling and taking really big hits. But to be able to withstand this kind of abuse, they have to be a little beefier and therefore heavier. Most cross-country riders prefer the compromise of a shorter-travel fork – it will still smooth out the ride, but without adding as much weight as a true downhill fork will.

What is Damping?

Damping is how the fork controls the speed of movement through its travel. There are two kinds: Compression Damping refers to controlling the movement as the shock compresses as it hits a bump. Rebound Damping refers to controlling the movement as the shock extends back to its relaxed position.


Fork Selection

What kind of fork can I install on my bike?

The first thing you need to do is to determine what size of headset you have. To do this, measure the diameter of the steerer tube, which comes up out of where your fork blades meet above the wheel. This is the part that runs up into your head tube. Most mountain bikes require 1 1/8", while 1" is standard for most road applications.

This measurement, which is usually 1", 1 1/8" or 1 1/4", and will determine what fork you can mount on your bike. The standard size for '02 mountain forks is 1 1/8". The new forks will also require a "threadless" headset that will fit your head tube size and a new stem.

The new "threadless" system has several advantages over the old threaded system as it is a lighter weight and stiffer connection, meaning that you will have better control of your front end. Because of the complexity of mounting the new headset and cutting the new fork steerer, it is recommended that you have your local shop install your new fork for you.

We have several headsets and stems available on our web site when you are ready to proceed with that part of your conversion.

How will a new fork affect my frame geometry and the overall ride of my bike?

Before purchasing a fork, carefully consider the geometry of your frame. Unless your frame was designed specifically for a suspension fork, adding a shock with a large amount of travel will dramatically change the handling and geometry of your bike. If you do want to add a suspension fork, consider one with a travel of 80mm or less.

Similarly, if you already have a frame with a long travel rear suspension setup, you'll want to choose a suitable long travel front fork to complement the rear suspension.

How do I choose between a conventional and thru-axle fork?

A thru-axle fork provides maximum stiffness and better overall performance for downhill bikes. A conventional axle fork provides compatibility with older wheels and faster wheels changes in the event of a flat. Typically, a thru-axle fork will only be used on a downhill specific bike. Remember that your front hub must match your choice of fork.


Accessories

What kind of accessories are available for my suspension fork?

Pumps for specific brands of forks are available to maintain the proper air pressure, as well as shock boots fitted to specific brands/models.


Advantages of Suspension

What is the difference between a cross-country and a downhill fork?

Mt. Forks come in two general varieties, cross-country or downhill. Cross-country forks will vary from 63mm to 100 travel and are mainly mounted on front suspension frames. Downhill forks usually have a dual crown to beef up rigidity. Travel is from 100mm to 180mm and are mounted on full suspension frames built to handle this type of fork.

Maxxis Crossmark

I bought crossmark 2.1 yesterday for my Patrol, thery subtitute my previous 2 years old maxxis highroller 1.95

. Here the review of crossmark from other, 

since I don't test it yet.

Maxxis CrossMark UST a review from mtbonline

I have been riding these for about 4 weeks now. Most of the riding has been on hardpack and a little in the mud (at Forest to Falls).

These tyres are intended for XC racing, so straight out of the box you expect them to roll fast. And they do. They do roll with ease. I find them “slower” than running the foldable Larssen TTs but this is because the foldables are significantly lighter than these, almost 200g.

Having said that, the new CrossMarks have a thing called LUST which stands for Lightweight Ultimate Sidewall Technology and what this means to you and me; is less chance of sidewall cuts, and it is in this department that I have been extremely impressed.

With all the sort of “urban” mountain biking that most of us do in JHB and Pretoria, tyres can take a real beating with glass, rocks etc. I have not had any problems with the CrossMarks. I have heard dreadful pinching noised as I speed over rocks, but no flats. In fact, I have not yet had a flat with these at all.

How do they look?

Well if you have seen the Larssen TT and the Mimo? You will notice some similarities with the CrossMark. The side knobs are a combination of the 2 tyres but then there is a big square knob running down the middle. Think if the TT and the Mimo had a love child, but because they are cousins there is sort of an abnormality. Giving birth to the CrossMark. The big square knob has sort of a cross in it resembling the Swiss flag.

The tyre was developed in conjunction with Christof Sausser. This was while he was riding for Siemens Cannondale last year, so ironically enough he will never be seen riding it as he can only ride the big S products this year.

By their own admission the tyre does not corner that well. On the box they only rate it 2 for cornering out of 4 and rate it 4 for rolling resistance. But I find that the tyre corners very well. Over the last couple of weeks I have grown more confident and have really been whipping my bike in the singletrack and the tyres have not let me down. I am running them at about 38 PSI and this seems to be the sweet spot. Lighter riders can push it down to 35 PSI.

I have also been impressed with the mud performance. Even though they are not intended for mud riding at all, I had them on at Forest to Falls and the mud cleared far better than the TT’s that I had on for Barberton and Haenertsburg.

We will be riding these for the Epic this year. Yes there is a weight penalty over running foldables! But the puncture and sidewall protection are a must for the event.

Oh, and they won’t break the bank! I paid R345 per tyre. Compared to my other favorite the Racing Ralph this is about R250 cheaper per tyre!!

Gn. Sindur” FULLMOON” Nightride

Setelah sekian lama ingin mencoba NR (baca: Night Ride), akhirnya undangan itu pun datang juga. Om Green T lewat sepedaku.com mengundang secara terbuka kepada semua biker utk menjajal trek Gunung Sindur di malam hari. Apa ya rasanya? Bagaimana mempersiapkannya?

Gn. Sindur” FULLMOON” Nightride ; UNDANGAN TERBUKA DARI OM GREEN T
« on: September 02, 2008, 10:08:16 PM »

Mengakomodir temen-temen yang sudah sakaw untuk gowes dibulan puasa, kami dari sebagian goweser JPG mengajak rekan-rekan yang kebetulan ingin sekali NR, atau belum sama sekali merasakan NR offroad,untuk jalan bersama menikmati indahnya trek offroad JPG-Gn.Sindur yang bermandikan terang cahaya purnama.Yang menurut perhitungan kalender Jawa jatuh pada hari Sabtu Wage 13 September 2008, meski belum purnama penuh.

Jarak tempuh JPG-Gn.Sindur-JPG kurang lebih 40 km, flat dengan variasi tanjakan dan turunan yang tidak begitu extrim, kami usahakan 90% adalah trek offroad dengan didominasi single trek, yang melalui beberapa perkampungan, lahan terbuka dan kebun bamboo yang lumayan serem, juga tak lupa KUBURAN CINA yang sangat luas yang bikin bulu roma berdiri (ada foto session , kalo mau!!)
Waktu tempuh diperkirakan start setelah solat tarawih, dan finish menjelang saur (gowes tidak terlalu cepat).

Hal-hal yang perlu dipersiapkan:

1. Ijin dari perdana menteri (menurut pengalaman agak susah), kesempatan 2 minggu ngerayu istri mungkin bisa berhasil.
2. Persiapkan fisik anda dan sepeda anda dengan prima.
3. Siapkan tools standart bersepeda, spt kunci ,ban dalam dll.
4. Siapkanlah lampu khusus sepeda, disarankan menggunakan 2 lampu, LED(kedip2) warna putih, dan lampu halogen warna kecoklatan.Masing masing punya kelebihan dan kekurangan, LED tahan lama tapi kurang terlihat kontur tanah offroad di malam hari.Halogen terang dan jelas untuk trek offroad tetepi boros di batere, kecuali memang anda sudah hapal trek dan berpengalaman NR lampu apa aja ok. Efek dari terang tidaknya lampu berpengaruh pada keseimbangan anda bersepeda.
   Siapkan juga batere cadangan.
   Siapkan (kalo ada) hidro pack, agar lebih mudah anda minum.

Hal-hal yang perlu diperhatikan di perjalanan:

1. Selalu masuk dalam rombongan jangan sampai anda terpencar, bergitu tersesat segera hubungi teman atau leader by telepon. Pengalaman ada yang tercecer ditengah hutan bamboo, yang nyari juga takut hehehehehe……. 
2. Selalu ucapkan salam, kepada penduduk sekitar yang kita lewati.
3. Ditempat-tempat tempat tertentu diusahakan tidak bercanda secara berlebihan……hiihihihihi……..
4. Nikmati perjalanan , jangan banyak mengeluh INI YANG TERPENTING…..hehehehehe…..
   

Waktu dan tempat

• Hari        : Sabtu 13 September 2008, Jam 20.30 WIB
  

• Tempat : Mpok Café JPG, Lengkong Gudang Timur BSD, Serpong.
  

Akan sangat berbahagia sekali bila rekan-rekan sudi untuk mencoba NR kali ini.

Salam Gowes

Tips from Shimano

What is the best way to clean the Shimano chain on my mountain bike?

Due to the harsher conditions associated with off-road riding, it is recommended that the chain be sprayed with a citrus based degreaser and wiped clean making sure all of the dirt and grime is removed from the outer faces of the plates. It is recommended that the chain is dry before applying a drop of lubricant to each link. Wipe off any excess lubricant before riding to prevent the accumulation of dirt and sand.

How do I know when to change my chain?

There are a number of tools on the market, including the Shimano TL-CN41, that will allow you to check for wear on your chain by measuring the amount of stretch. You will want to change your chain between 0.075mm and 0.1mm of stretch.
What should I use to clean my disc brakes?
Isopropyl Alcohol is the best choice for cleaning Shimano disc brakes. It cuts through the mineral oil, grime, brake dust, and other foreign matter, dries quickly and leaves no residue


How can I prevent my disc rotors from rubbing while I'm coasting or pedaling?
In most cases, this scenario is due to incorrect installation to the frame/fork or a lack of maintenance. Check to see if the calipers are properly bled and positioned correctly, the rotors are perfectly true and frame's suspension links are all in good condition. It is highly recommended that the mounting tabs on the frame and fork have been properly spot faced to ensure accurate alignment with the rotor. Because bicycles are designed to be light as possible, it is unavoidable to have small flex in the frames and wheels while riding. This small flex may be enough to make your rotor rub when you're coasting or pedaling. Depending on the riding conditions, disc brake calipers need cleaning and maintenance on a regular basis. Wet and muddy conditions will require a more frequent service interval than dry riding conditions. Also, inspect the disc brake pads for wear. Replace the pads when the pad material has worn to a thickness of 0.5mm or less.


What are the differences between the metal and resin disc brake pad compounds?
Metallic pad compounds offer greater braking power and more resistance to heat-induced fade.

Resin pad compounds offer better modulation and less noise.

How interchangeable are Shimano's hydraulic disc brake systems?
All Shimano hydraulic disc brake systems are interchangeable. Depending on the model of the brake lever and caliper, the connections may differ and could require replacing of the hose and/or the connection fitting, but the brake levers and calipers are fully compatible.

How do Hollowtech II cranks fit the variety of mountain bikes available?
By using the supplied spacers in the correct positions, Hollowtech II cranks are able to adapt to both 68 or 73mm bottom bracket shells with or without an E-type derailleur.

Can I use other brands of disc brakes with the Shimano Center Lock rotor system?
Shimano doesn't approve other brands of disc brakes to be used in conjunction with our Center Lock rotors. For best performance and safety Center Lock rotors should only be used with Shimano disc brake calipers.

Why should I use a torque wrench when installing Shimano components?
By properly using a Torque Wrench to check the bolts during assembly and follow up service you can be sure that the bolts have been tightened correctly. In some cases to tight or too loose will have a dramatic effect on the performance and safety of the components.

Ho do I Choose A Right Bike?

A common misconception is that a new rider needs more suspension because of the added control. While the added suspension may instill confidence in some technical sections, often time the relaxed geometry is not suited to less experienced riders.

On the other hand, it is just as hard to avoid the temptation of the ultra-light bike. The benefits of light weight are undeniable, but a novice rider will find XC racing bikes can be difficult to control when the trail gets rough.

XC Racing Bikes



Often called Cross Country bikes, XC Racing bikes are designed to tackle a mountain from the bottom. Lightweight and efficient, XC bikes often sacrifice comfort and control as luxuries you can’t afford when racing to the top.

XC bike frames are either hardtail or short travel, semi-active suspension designs. Long and low, XC bikes put the rider in a stretched out position. Best suited to gradual terrain, XC racing bikes are popular in areas without a lot of rocks and roots and among competitive riders.

If your idea of mountain biking is fitness and endurance you may want to consider a XC Racing bike. If you consider the best rider the one who made it to the top first, then your choice is made.

XC Trail Bikes



Often called all-purpose, XC Trail bikes are what most people think of when they hear the term “mountain bike”.

XC Trail bikes are designed to climb with control and comfort and descend with speed. With active suspension, knobby tires and low gearing the XC trail bike is slightly less efficient than an XC Racing bike but can be more enjoyable to ride downhill. As terrain gets steeper, trails tend to get rockier and the ultra-light XC Racing bike may ride roughly, but the XC Trail bike is right at home.

If you like the idea of challenging yourself on a rocky climb, enjoy extended singletrack descents and want to battle it out with your friends going uphill or down, an XC Trail bike may be for you.

All-Mountain Bikes



Some riders just need more. As adventures get longer and trails more remote, many riders see increased value in reliability and downhill control.

The bigger tires, plush suspension and powerful brakes of the All-Mountain bike are an insurance policy against accidents and mishaps and can be just plain fun to ride. With geometry suited to steep terrain and small drop-offs All-Mountain bikes can inspire confidence, however, on more mild terrain they can feel sluggish.

If you are an all-day adventurer or ride harsh trails you may be an All-Mountain rider.

Freeride Bikes



Freeride bikes are designed to ride the most extreme types of terrain. Steep chutes, large rocks and roots, big jumps and drop-offs, and just about anything else, natural or man-made, that you can imagine.

With only the occasional concession made for even the thought of riding uphill, freeride bikes are mountain biking’s version of monster trucks. Blurring the line between bicycle and motorcycle, bikes with eight inches of rear wheel travel, three inch wide tires, and eight inch diameter brake rotors are commonplace.

If you are attracted to the challenge of going big and see mountain biking as a source of individual expression, Freeriding will appeal to you. And what does any extreme athlete need? Well, a Saint to watch over him, of course.
