Technology

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.

Tapered Seat Tube (MTB)

Increases riding comfort and provides stiffness and drive-train efficiency.

Hydroforming (MTB)

A bonus in steering precision and longevity.

Tapered Steerer / Tapered Headtube (MTB)

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

Triple Butted, Double Butted

For light and stable frame: Frame tubes with thinner walls in the middle and thicker walls at the ends.

QR15 Front Thru-Axle (MTB + ATB + Pedelec)

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.

Smooth Welded

Smooth welds reduce notching and make aluminium frames more durable.

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.

Tapered Seat Tube (MTB)

The seat tube tapers from top to bottom. At the top it fits a slim seatpost that offers some flex and therefore increases comfort especially when riding over rough ground. At the bottom the large diameter nicley flows into the bottom bracket shell and downtube to provide great stiffness and drivetrain efficiency.

Hydroforming (MTB)

Using water pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers and designers.

Tapered Steerer / Tapered Headtube (MTB)

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.

Triple Butted, Double Butted

Meaning a frame tube has three or two different wall thicknesses along its length. Triple butted (TB) is the usual technology with STEVENS high-quality frames.
Tubes with different wall thicknesses are optimally adjusted to certain ways of manufacturing or to withstand specific loads. Where the highest loads occur or where tubes are welded, walls are the thickest. Butted tubes allow frame weight to be lower by several hundred grams.

QR15 Front Thru-Axle (MTB + ATB + Pedelec)

"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.

Smooth Welded

Additional step in welding. The first, rippled weld, typical for aluminium, is covered with a second smoother weld. This not only improves looks but also lowers the risk of notches in this spot, which makes the frames more durable.

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.
