The Superior Marathon and Trail Machine.

First prototypes and pre-production samples had to proof themselves in competitive racing - but now the brandnew Jura Carbon ES is ready for your fun rides and races to victory. With a light and stiff full carbon frame, new electronic XT 2x11-speed drivetrain and many other high-class components. With 27.5" or 29" wheels depending on frame size. And 100% ready for marathon/XC races and fast trail riding.

  • Full carbon bike with four-pivot suspension and superiour marathon geometry
  • Responsive Fox Float Performance Elite chassis (120/120 mm)
  • High-quality DT Swiss wheels plus very fast Schwalbe Rocket Ron tires
  • Full Shimano Deore XT 2x11 groupset
  • Classy Syntace cockpit up to carbon seat post

Technology

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.

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.

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 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.

Di2-Akku-Box

Systemlaufräder

Um die elektronischen Schaltkomponenten noch besser zu integrieren, befindet sich im Tretlagerbereich der STEVENS Carbon-Fullys eine Öffnung, die Montage und Wartung des zugehörigen Akkus zur leichten Übung macht.

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.

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.

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.
