Le vélo de Marathon et de Trail de qualité supérieure.

Les prototypes et les vélos de pré-production ont, d'abord, dû faire leurs preuves en compétition. Aujourd'hui, ils sont prêts pour servir la gagne ou le fun. Avec un cadre tout en carbone léger mais rigide et la fourche suspendue innovante Fox 34 Step Cast. Avec un groupe complet Shimano Deore XT 2 x 11 vitesses et de nombreux autres composants haut de gamme, dont une tige télescopique. Avec des roues spécialement adaptées à la taille du cadre (27,5" ou 29" de diamètre). Et 100 % prêt pour les courses de marathon/cross-country ou les trails rapides.

Rearshock Development

Diffferent purposes in different terrain require different ride properties. This is why every fully rear triangle receives a specific setup from STEVENS' engineers to meet the respective bike's requirement for optimum performance. Firm for minimum power loss in the marathon with lots of comfort for long distance riding with a linear characteristic curve and mind-soothing reserves for hard hits.

Dropper Post

Optimum seating level for best drivetrain efficiency. Push the button: saddle down for best clearance on technical descents. Push the button: saddle up … this could go on forever - and on some technical trails the dropper post remote will be actuated more often than the front derailleur shift lever. Experts for fun and safety alike agree: Very rarely has an innovation meant so many convincing advantages and so little disadvantages like a dropper post with infinitely adjustable seat height.

Boost-Standard Fork

What is right for the rear wheel is even more important at the front wheel - because steering precision matters. This is why STEVENS uses suspension forks and hubs with extra wide axle spacing for this bike. These 110mm of axle spacing are called "Boost" or "Plus" and stand for lots of added lateral stiffness plus space for extra wide studded tires.

Boost Rear Axle Spacing

This bike adheres to the "Boost" standard with 148 mm axle spacing. And there are good reasons for that. Rear wheel stiffness increases by 20 % which is especially beneficial in large 29" wheels. And there is more space for voluminous studded tires to give you more control and fun an the trail.

High Modulus Carbon Fibers

Only the very best materials are used for the highest quality STEVENS carbon frames - so called high modulus carbon fibres. They offer a perfect combination of maximum toughness and targeted elasticity. This way they provide maximum lateral stiffness for best forward drive and a high amount of comfort. Result: incredibly light and enormously stiff frames.

Versatile cable routing

We keep the cable routing on our bikes as versatile as possible so you can ride your bike like you want to. There are wide and therefore easy to reach cable ports in the frame to insert shift or brake sleeves, Di2 cables or even no sleeves at all - there are the appropriate cover plugs for all of this.

Tapered Steerer / Tapered Headtube

Fork shaft (or steerer tube) and head tube are tapered, meaning their diameter increases from top to bottom resulting in a conical shape. The diameter needs to be bigger at the bottom since this is where higher stress is applied - especially when the bike has a higher total weight due to luggage or an e-drive and battery. Also tapered steerers feature a smoother force transfer (like forces caused by hard braking) to the downtube than forks with a continuous 1 1/8" diameter.

QR15 Front Thru-Axle

"15" stands for the diameter in millimeters, "QR" for quick release. Combined they are the most useful method to fix the front wheel to the (suspension) fork. With convincing advantages: high stiffness, precise positioning of the brake disc and super-easy handling. So STEVENS specs almost all its mountain bikes and even high-quality trekking bikes, cross bikes and pedelecs with a thru-axle. Additionally, especially with 29" MTBs axle spacing is increased from 100 to 110 mm which makes the design even stiffer.

E-thru Rear Axle

E-thru Rear Axle at E-Cayolle

This abbreviation stands for Shimano's thru-axle standard for rear stays that integrates a thread into the dropout. As a result, the 12mm thru axle provides outstanding rear triangle stiffness and utmost precision in brake disc alignement to prevent annoying brake rub.

Chain Stay Protector

Now you can tackle any downhill ramp without worry: The specially fitted chain stay protector prevents the chain stays of STEVENS carbon fullies from getting damaged by a slapping chain.


Electronic shifting is already well established in road bikes as well as in mountain bikes next to classic mechanical systems. Impressively fast and reliable gear changes and minimum maintenance pay their dividends not only at the Tour de France, in cyclocross or on the Cross-Country World Cup circuit. That's why STEVENS road bike and MTB frames are "Di2"-ready, meaning they are prepared for an elegant integration of batteries and electric cables (instead of usual wire cables). Even for the classy Alfine gear hub Shimano offers an electronic version.
