Endurance Racer? Test Winner!

Our "Bull's Eye" (according to RoadBIKE magazine) performs perfectly in the 2200-Euro-category with its 1100 gram (2 lbs.7 oz.) full carbon frame including a precisely steering fork with tapered shaft. Removing any shadow of doubt, it's spec'd with top performing Shimano Ultegra 11 speed gruppo, wheels from DT Swiss and premium 25mm Continental tires.

  • Light pro-level frame with carbon dropout
  • Pressfit inner bearings and integrated brake/shift cables
  • Full carbon fork with tapered steerer
  • Shimano Ultegra groupset w/ semi-compact crank
  • High-end tires: Continental GP 4000 S II (25 mm)

Technology

Full Carbon Fork

The most intelligent way of lightweight design for STEVENS engineers is to use carbon forks with 100% carbon fibers that run all way though from dropout to steerer tube in one single piece. This results in an amazing riding experience on and off-road: Lightweight, knife-sharp steering precision effortless climbing and maximum lateral stiffness even when combined with disc brakes.

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.

Comfort Carbon Seatpost

Who wants to be fast does not need to suffer – especially not when their STEVENS Carbon road bike is equipped with a Scorpo Carbon SL Comfort Seatpost which filters annoying road buzz. Its diameter of 27.2mm only and dedicated fibre orientation enable better flex without adding weight or loosing stability. By the way: the post can also be retrofitted.

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. Riders will benefit from a noticeable higher steering precision almost without weight penalty. 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.
