Whatever you think of the design, the result is clear: it's the fastest bike we've ever measured, and it combines this with the outstanding suspension comfort of the Isospeed seat tube. The top tube and seat tube are connected by a ball bearing that allows the seat tube to flex over its entire length. Fully integrated cables and brakes are also responsible for the aero result. The brake cables run through the handlebar/stem unit into the frame and from there to specially designed centre-pull brakes. The only points of criticism: the cork brake pads and the in-house tyres; there is still potential for tuning here. The sleek wheels are tubeless-compatible, and in addition to the radical racing geometry, a more moderate version with a longer head tube is also available.
CONCLUSION Outstanding aerodynamics, comfortable, successful integration solutions. A bike that sets standards, even in terms of price
