The Trek Madone Gen 8 redefines the benchmarks of high-performance road racing bikes by merging the featherweight agility of a climbing bike with the raw aerodynamic velocity of a flat-out aero chassis. Built from Trek’s top-tier 900 Series OCLV Carbon, the frameset leverages Full System Foil tube shaping alongside the revolutionary IsoFlow seat tube technology, absorbing road chatter while cutting cleaner through the wind. Tipping the scales at a race-ready 7.52 kg (Size ML), it delivers explosive power transfer whether launching an attack on an alpine pass or sprinting for the line.
Outfitted with a full Shimano Ultegra Di2 R8170 / R8150 12-speed electronic drivetrain, the build features seamless, wire-free shifting combined with high-modulation hydraulic braking. Rolled on Bontrager Aeolus Pro 51 OCLV Carbon tubeless wheels and steered via the ergonomic Trek Aero RSL integrated carbon bar/stem, every detail is optimized for aerodynamic efficiency. Embracing modern standards, the Gen 8 frame comes equipped with a threaded T47 bottom bracket and a universal SRAM UDH derailleur hanger dropout, allowing effortlessly precise shifts and high-end aftermarket hanger customization.
