A road bike with discs under 6 kg? - Articles Sports equipment

The foundation of this Émonda SLR climber is Trek's exclusive 700 Series OCLV Carbon Frame, the lightest and strongest carbon you can find. It incorporates Flat Mount disc brakes that are lighter, smaller and more discreet than conventional disc brakes.

The assembly did not skimp on achieving the lowest possible weight, opting for the top-of-the-range components of the Bontrager XXX series for the saddle, the handlebar / stem assembly and the Aeolus XXX 2 Disc wheels, with 28 mm profile and 1.150 grams of weight in tubular version.

Assembly is completed by the new SRAM Red eTap AXS.

But the fundamental thing is that with the program Project One, the barrier of 6 kg has been lowered. with standard parts and without compromising safety at critical points on the bike.
