Trek Madone SLR 9 8th Gen Sram Red E1 12-speed road bike Bontrager Aeolus RSL 51 Purple Phaze Amethyst Marble 2027

The 8th-generation Madone SLR 9 Trek is designed for cyclists looking for an uncompromising race bike. Its 900 Series OCLV carbon frame, combined with Full System Foil aerodynamic profiles and IsoFlow technology, offers a remarkable balance between lightness, efficiency and comfort. Weighing just 7 kg in size ML, it’s as explosive on climbs as it is fast on open roads, with a precision that makes you want to accelerate straight away.

Its top-of-the-range spec lives up to its ambitions. The RED AXS E1 2x12 ‘ SRAM ’ drivetrain with power metre ensures fast and precise gear changes, whilst the Aeolus RSL 51 OCLV carbon wheels from the ‘ Bontrager ’ range deliver excellent aerodynamic efficiency without compromising the bike’s handling on hills. The integrated Aero RSL Trek cockpit completes the package with a race-oriented riding position and exceptionally clean integration.

Designed down to the smallest detail to maximise efficiency, the Madone SLR 9 completely conceals its cables and benefits from a cohesive design right down to its RSL aerodynamic components. It is a true racing machine – light, responsive and fast – capable of turning every pedal stroke into speed whilst retaining enough comfort to remain competitive as the kilometres mount up.
