Credit goes entirely to Trek's awesome IsoSpeed'decoupler' a mechanical pivot at the seat tube-top tube intersection and the Madone's clever dual, nested seat tube design that, in combination, allows for much more flex at the saddle than you'd otherwise get out of a more traditional frame. Unlike on Trek's similarly IsoSpeed-equipped Domane endurance platform, which incorporates an even cushier rear end but can sometimes feel somewhat harsh up front, the new Madone delivers up a more balanced and cohesive feel front to rear.It might not be as comfortable out back as a Domane but then again, as a full-blown race bike, it should be firmer and more communicative. That all said, riders interested in an aero road bike aren't going to be considering ride quality as their primary metric we're talking about free speed, after all, and this new Madone seems to have that in spades, too. As expected for this segment, the chassis is plenty stiff, too. Boulder isn't exactly known for being flat, however, and the countless canyon roads to the west also demand plenty of braking. Thankfully, the new Madone's proprietary center-pull rim brakes are not only cleanly integrated into the frame and fork for aero purposes but they also work well a good thing since there are no other options. Caliper flex is practically nonexistent thanks to short and compact aluminum arms and a fully boxed-in layout that bridges the ends of the direct-mount pivots. Meanwhile, the cable wedge moves on rollers while both pivots are fitted with cartridge bearings to return a silky smooth and light lever feel that's noticeably devoid of excess friction. Trek officially says the new Madone will swallow tires up to 28mm wide and rims up to 30mm wide (external measurement), depending on the exact combination.
