The seat tube angle is adapted in order to harmonize riding comfort and the correct sitting position. The bended rear triangle makes best bump absorption possible while a tapered head tube assures high steering precision. The stiffness optimized bottom bracket construction in combination with a pressfit BB lead to an unmatched acceleration. Thus every pedal step is transferred directly on the road. The rear derailleur hanger has an integrated cable stopper and the right chainstay has an integrated chainstay protection shield. The cable routing is also integrated and thus protection and a clean lookout assured. The frame is compatible with mechanical and Di2 shifting.
