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.

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.

Chain guide interface

To prevent the light aluminium chainstays of STEVENS fullies from scratching, we use high-quality bolt-on protectors. They also house a little, smart chain guide directly underneath - the Bionicon c.guide eco (available at your local bike dealer). The c.guide also provides a quiter drivetrain and keeps the chain securely on the chainrings.

Side Swing front derailleur

Side Swing Umwerfer
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.

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.

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.

Anodized Frames (Anodized finish)

In an electrically charged dipping bath high-quality aluminium frames are covered with a hard, smooth, even surface that looks especially classy in STEVENS Anodized Black. Therefore neither a paintjob nor powder coating is necessary - saving about 200 grams of frame weight.

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.

E-thru Rear Axle

This abbreviation stands for Shimano's thru-axle standard for MTB rear stays that integrates a thread into the dropout. On the majority of STEVENS mountain bikes a 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.

Kettenstreben-Protektor

Damit Ihr bedenkenlos jede Piste herunterjagen könnt: Der speziell angepasste Protektor schützt die Kettenstreben der STEVENS Carbon-Fullys vor heftigen Kettenschlägen.

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.
