Moving ahead.

The addition "Race" as well as the bright red accents are the starting signal. This extremely fast crosser only knows one direction: onwards. Driven by the complete Shimano Deore XT 2x11-speed groupset. Even lighter with a weight starting at 11.9 kg. And controlled via the ergonomically shaped Oxygen cockpit with a handlebar width of 640 mm as well as strong Deore XT disc brakes. The only thing you need to add is a powerful motor - your strong legs ...

  • Race oriented top cross bike for asphalt and gravel roads
  • Innovative triple butted aluminum frame with smooth welds
  • SR Suntour air suspension fork w/ thru-axle and lockout remote control
  • Full Shimano Deore XT 2x11 groupset
  • Strong Shimano Deore XT disc brakes

Technology

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. Riders of allround bikes and pedelecs will benefit from a better stability caused by hydroforming even when they are touring with heavy luggage.

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.

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.

Hydraulic Disc Brakes – Trekking

There is no more reliable brake system than hydraulic disc brakes - that is why we strongly advice everyone, who is riding their cross, trekking- or city bike 12 months a year to choose one of our models with the „DISC“ suffix. Brake power is easy to modulate and does not fade a bit in the wet. Also the brakes are almost maintenance-free. And your local STEVENS dealer will gladly explain to you what you need to take care of when removing and re-installing a wheel
