Our World Cup and trail rocket.

In its first season it already won a podium placing in the Albstadt World Cup race - and now the STEVENS Jura SL is ready to be ridden to victory or for fun. With a light but stiff full carbon frame, new Fox 34 Step Cast suspension fork, Shimano XTR/Race Face 1x12-speed drivetrain and many other top-shelf components including a Fox dropper post. With frame size specific wheels in either 27.5" or 29" diameter. And 100% ready for marathon/XC races or fast trail riding.

  • Full carbon bike with four-pivot suspension and superior marathon geometry
  • High-end Shimano XTR/Race Face 1x12-speed drivetrain & Shimano XTR disc brakes
  • Superior Fox Float Factory chassis (120/120 mm) with super-light step-cast fork
  • DT Swiss XR 1501 wheels plus lightning fast Schwalbe Rocket Ron tires
  • Classy Syntace cockpit plus Fox Transfer dropper 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.

Shimano Di2

Systemlaufräder

No other shifting system changes gears as fast and reliable as the electronically actuated Di2 option for Shimano's XTR and XT group. From fine tuning to preferred shifting speed all adjustments can be done via the handlebar display - in case of XT even with a smart phone app and Bluetooth link.

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 fullies, as well as for the trail rocket Sonora and the alloy-hardtails Colorado and Sentiero. 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

Since model year 2016 the rear stays of all STEVENS fullies adhere to the new "Boost" or "Plus" 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.

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.

Chain Stay Protector

Now you can tackle any downhill ramp without worry: The specially fitted chain stay protector prevents the chain stays of STEVENS carbon fullies from getting damaged by a slapping chain.

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.
