Anyone who doubted that aerodynamics and lightweight construction go together will be proven wrong by Trek. At 353 watts (with Cosmic Carbone SL; 349.7 watts with Trek's own Aeolus 5 wheels), the top model of the Madone series built in the USA delivers a good aero result, while at the same time the frameset is one of the lightest ever at 1,176 grams. This weight is made possible, among other things, by a special paint that is said to weigh five grams and - no joke - costs an extra 1,000 euros. There are probably two main reasons for the aero result: the Kammtails known from the SpeedConcept time trial model - aero profiles cut off at the rear to optimise flow and save weight - and extremely narrow fork blades. The latter produce the only discordant note in the test report. The fork has above-average lateral compliance, but this is largely compensated for by the stiff frame. Thanks to the Ride-Tuned seatpost, the bike is also very comfortable on the saddle. Advantage for licence riders: Because the frame is so light, the bike is lighter than the 6.8 kilos permitted by the UCI, even with top aero wheels.
