Technology

Boost-Standard fork

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

Boost-Standard am Hinterbau

Seit dem Modelljahr 2016 entsprechen die Hinterbauten aller STEVENS-Fullys dem neuen „Boost“.

Tapered Seat Tube

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

Hydroforming

A bonus in steering precision and longevity.

Shimano Side Swing Umwerfer

Blitzschnelle, leichtgängige Gangwechsel dank innovativer Mechanik von Shimano.

Versatile cable routing

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

Tapered Steerer / Tapered Headtube

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-Steckachse vorn

Die funktionellste Methode, das Vorderrad in der (Feder-)Gabel zu verankern.

Smooth Welded

Smooth welds reduce notching and make aluminium frames more durable.

Di2-ready

Vorbereitete Rahmen für elegante Integration von elektronischer Schaltung.

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 all its 29er fullies, the Whaka+ ES and the trail rocket Sonora SL. 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-Standard am Hinterbau

Seit dem Modelljahr 2016 entsprechen die Hinterbauten aller STEVENS-Fullys dem neuen „Boost“- oder „Plus“-Achsmaß mit 148 mm Einbaubreite – und das hat gute Gründe: Die Seitensteifigkeit des Hinterrades erhöht sich um ca. 20%, wovon vor allem die großen 29er-Laufräder profitieren. Und es wird Platz geschaffen für voluminöse Stollenreifen, die auf dem Trail mit besserer Performance und mehr Fahrspaß punkten.

Tapered Seat Tube

The seat tube tapers from top to bottom. At the top it fits a slim 27.2mm 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

Using water or oil pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers to perfectly withstand any load without any weight penalty. This means better steering precision on the trail and higher longevity.

Shimano Side Swing front derailleur

Our top supplier Shimano made a great innovation here. One that works reliably on any terrain when changing gears at the front has to be fast and precise - be it in competitions or on technical trails. Thanks to its upright axes the front derailleur cage swings outward and forward at the same time, and due to its direct actuation from the downtube only needs minimum operating force.

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 either one or two cables or none at all - there are cover plugs for any of these configurations. This is also very convenient for retrofitting a dropper post.

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.

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-Steckachse vorn

Die „15“ steht für den Achsdurchmesser, das „QR“ für „Quick Release“, also Schnellspanner – und zusammen für die funktionellste Methode, das Vorderrad in der (Feder-)Gabel zu verankern. Die Vorteile sind bestechend: hohe Steifigkeit, präzise Bremsscheiben-Positionierung und kinderleichte Bedienung. Also stattet STEVENS fast alle Mountainbikes und sogar die hochwertigsten Trekking-, Crossbikes und Pedelecs damit aus. Vor allem bei den 29“-MTBs wird sogar noch die Einbaubreite erhöht – von 100 auf 110 mm, das ist noch steifer.

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.

Di2-ready

Elektronische Schaltungen haben sich am Rennrad und am Mountainbike neben den klassischen mechanischen Schaltungen längst etabliert. Bestechend schnelle und zuverlässige Gangwechsel bei minimalem Wartungsaufwand machen sich eben nicht nur bei der Tour de France oder im Cyclocross-Worldcup oder auf den Cross Country-Weltcup-Strecken bezahlt. Und genau darum sind viele Rennrad- und Mountainbikerahmen von STEVENS bereits „Di2-ready“ – sprich: für die nahtlose Integration von Akkus und Kabeln (anstelle der herkömmlichen Seilzüge) vorbereitet. Und selbst für seine edle Alfine-Nabenschaltung bietet Shimano eine Elektronik-Version an.

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.
