Trek Madone SLR 8 Disc Road Bike 2019

Constructed from Trek's own 700 Series OCLV carbon and with a rider position optimised to be fast and aero, thanks to the geometry of the H1.5 fit, the Trek Madone SLR 8 Disc Road Bike belongs at the front of the pack.

But speed doesn't come at the cost of comfort. The Adjustable Top Tube IsoSpeed lets you fine-tune the compliance for a road-smoothing ride quality and the adjustable Madone bar/stem combo, with +/-5 degrees of bar rotation, provides the widest possible range of fits for both men and women.

Reliable gear shifting comes from the precise 2x11 Shimano Dura-Ace mechanical drivetrain, and the Bontrager Aeolus Pro 5 Disc wheels, with D3 Dual Directional Design profile, cut drag at the tyre and rim-leading edges for a maximum aerodynamic benefit on the open road or in the heat of a sprint finish.


  • Trek 700 Series OCLV carbon frame claims to be the lightest and strongest available
  • Adjustable Top Tube IsoSpeed lets you customise the compliance to suit your ride style or terrain
  • H1.5 fit geometry puts the rider into an aero sweet-spot, primed for racing
  • Kammtail Virtual Foil tube shaping has undergone rigorous wind-tunnel testing to optimise the aerodynamic performance
  • Bontrager Blendr stem technology for custom light and computer mounting keeps the cockpit clutter-free
  • Invisible cable routing for an aero-optimised sleek look
  • Flat-mount hydraulic disc brakes are smaller, cleaner yet more powerful
