Teknologi

True monocoque frame

Only with this one-piece design all the advantages of carbon as a frame material can be exploited.

Boost-Standard fork

What is right for the rear wheel is even more important at the front wheel - because steering precision matters.

Boost Rear Axle Spacing

Since model year 2016 the axle spacing in the rear stays of all STEVENS fullies adhere to the new "Boost" standard.

High-Modulus Carbon Fibres

For incredibly light frames and utmost stiffness.

Versatile cable routing

To ride your bike like you want to: Versatile cable routing.

4-piston disc brakes

The most demanding riders are satisfied with nothing less in terms of braking performance and riding safety.

Di2-ready

Frames prepared for an elegant integration of electronic shifting.

Tapered Steerer / Tapered Headtube

Riders benefit from noticeably higher steering precision, almost without weight penalty.

QR15 Front Thru-Axle

The most useful method to fix the front wheel to the (suspension) fork.

E-thru Rear Axle

Thru-axle standard from Shimano for extra stiff rear triangles and precision in brake disc alignement.

True monocoque frame

True monocoque frame To make this frame, all carbon fibre mats are placed in ONE mould and then "baked" with the resin matrix to form a premium frame. Only with this one-piece design all the advantages of carbon as a frame material can be exploited: perfect design for the actual loads, optimum power flow from the head tube via the main frame and seat and chain stays to the rear wheel - and all this with minimum material requirements (= weight!). Many carbon frames on the market are instead assembled from several pieces.

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.

4-piston disc brakes

The demanding riders of high-end MTBs and touring e-bikes - with or without "E" support - are satisfied with nothing less than the most powerful hydraulic disc brakes in terms of braking performance and riding safety. They have 4 pistons per caliper instead of 2, and their larger brake pads can withstand much more heat, making them almost immune to fading (less friction due to heating).

Di2-ready

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.

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

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.

Bike-Category 5

Cross-country, marathon and touring mountain bikes

This category describes STEVENS cross-country, marathon and touring mountain bikes and is typically represented by STEVENS mountain bike hardtails and full suspension STEVENS bikes with short suspension travel. STEVENS MTB Marathon 120, Carbon XC, Alloy XC.

Instructions on intended use

The permissible overall weight (rider incl. baggage and bicycle) should not exceed 115 kg. Under certain circumstances the permissible maximum weight can be further limited by the component manufacturers’ recommendations for use.

The following weight limits for the rider including equipment and STEVENS bicycle apply to special wheels:

Mavic:	100 kg
DT Swiss:	110 kg

STEVENS cross-country, marathon and touring mountain bikes are suitable for off-road use, but not for blocked terrain, tricks, stair riding etc., training and competitive use in the categories freeride, dirt, downhill. STEVENS bikes of this category can be used on surfaces permitted for bikes of the categories 1 and 3 and are in addition suitable for rough and unpaved terrains. Sporadic jumps are also included in the field of use of these STEVENS bikes. But particularly inexperienced riders doing jumps may land inappropriately, thus increasing the acting forces significantly which may result in damage and injuries. We recommend that you train your skills in a riding technique course. If necessary, ask your STEVENS dealer to inspect your STEVENS bicycle at shorter intervals than according to the service and maintenance schedule.

For full suspension STEVENS mountain bikes trailers are not permitted.

Due to their design and fittings, STEVENS mountain bikes of the category 5 are not always suitable for being used on public roads. If you want to use them on public roads, these bikes must be fitted with the prescribed equipment. Observe the traffic rules when riding on public roads. For more information see chapter “Legal Requirements for Riding on Public Roads” in your comprehensive STEVENS user manual on the enclosed CD-ROM

Danger:

STEVENS bicycles of the category 5 are not suitable for use on blocked terrain, jumps, slides, stair riding, stoppies, wheelies, tricks etc.!

The mountain bike itself describing one particular type of bike does not exist any longer. Various types of mountain bikes for specific uses have been developed instead. Be sure to use your STEVENS mountain bike only according to its intended use. Observe the traffic rules when riding on public roads.
