Trek Domane 5.2 C 50cm - LAST ONE!
Trek's Domane 5 Series was developed for Fabian Cancellara to crush the cobbles of Europe.

Race-all-day geometry gives you the edge over the competition with confidence-inspiring handling while the specs keep you at the front of the peloton. An Ultegra drivetrain with compact cranks dishes out the silky shifting that Shimano is renowned for and Bontrager's tubeless-ready wheels are wrapped with 25c tires for the perfect combination of speed, low-rolling resistance and ride quality. Trek also keeps the 5.2 firmly in the featherweight class with a carbon handlebar, seatmast and fork.

Developed in close coordination with the cobbles-racing master, Fabian Cancellara, this feather-weight carbon rocket offers a rear IsoSpeed system that allows you to adjust and dial in the compliance based on your terrain, riding style, and personal preference. Taking endurance-oriented comfort even further, Trek adds IsoSpeed to the front end, decoupling the steerer tube from the head tube and increasing compliance by 10%. The Domane SLR 9 is built with Trek's premier 600 series OCLV carbon, with a wide BB90 bottom bracket that directs all your power to the road so that you’re as efficient as you are comfortable. Bontrager's tubeless-ready Aeulus 3 carbon wheels and 28mm-wide R3 tires offer a supple grip through sweeping descents and strength across pock-marked country roads. A full SRAM RED eTap wireless electronic drivetrain gives you perfect, effortless shifting and enough range to tackle the most daunting mountain passes, while powerful direct mount brakes minimize weight and control speed. Integrated into the frame, just below the bottle cage mount, the Domane Control Center houses the internal eTap battery. Bontrager provided their own touch to Trek’s long-distance horse with an IsoCore handlebar. A continuous layer of thermoplastic elastomer encased in OCLV carbon reduces high-frequency vibration to keep your hands and shoulders comfortable, even on long stretches rough roads. The Domane SLR incorporates hidden fender mounts for those epic Rule #9 days, a 3S chain keeper for confidence across rough roads, and DuoTrap S integration for sleek data transmission.
