Trek Madone SLR 9 AXS Gen 8 2026 - Road Bike
The Trek Madone SLR 9 AXS Gen 8 is the fastest road bike Trek has ever made built with input from elite pros and refined across eight generations to deliver class-leading aerodynamics, stiffness and comfort. At the core is Trek’s 900 Series OCLV Carbon, shaped using Full System Foil tube profiles to minimise drag across every tube junction, improving airflow whether you’re sprinting or powering over climbs.
Key Features:
- 900 Series OCLV Carbon frame with Full System Foil aero shaping and IsoFlow seat tube
- Madone Gen 8 full carbon fork with tapered steerer and internal routing
- SRAM RED AXS E1 2x12 wireless drivetrain with integrated power meter
- SRAM RED AXS E1 hydraulic disc brakes with Paceline X 160 mm rotors
- Bontrager Aeolus RSL 51 carbon wheels with RSL RD 700x28 mm tyres
- Trek Aero RSL one-piece carbon bar/stem and RSL Aero bottles & cages
- Available with 0% APR finance
The frame features the latest IsoFlow seat tube, which flexes to absorb road vibrations while also reducing weight and boosting aero performance. This Gen 8 version has been redesigned for 80% more vertical compliance, offering a smoother, more comfortable ride without compromising stiffness or efficiency.
Paired with SRAM’s flagship RED AXS E1 groupset, the bike delivers flawless, wireless shifting with fully customisable gear setup and haptic feedback from the shifters. The integrated power meter on the chainset lets you train and race with precision, while the 10–33 cassette ensures a wide range for punchy climbs and big-ring descents.
Braking is equally pro-level with SRAM RED AXS hydraulic disc brakes and Paceline X rotors offering strong, fade-free stopping power. Rolling performance comes from Bontrager Aeolus RSL 51 carbon wheels, matched to Bontrager RSL RD 28 mm tubeless tyres for race-ready speed and grip.
A fully integrated Trek Aero RSL carbon cockpit and Madone aero carbon seatpost round out a package that’s designed to maximise every performance edge. Even the included RSL Aero bottles and cages are shaped to reduce drag and match the frame lines seamlessly.
