Trek Madone SL 5 Gen 8 Road Bike in Gloss Fury Red/Matte Deep Smoke

Season:2026

Brand:Trek

Code:57653RED

The Madone SL 5 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point.

It offers similar aero benefits to the pricier Madone SLR Gen 8 models, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. A Shimano 105 group set, alloy handlebars, and alloy wheels keep the price down while still delivering clean mechanical shifting you can trust.

The Madone SL 5 Gen 8 was informed by feedback from Lidl-Trek's fastest sprinters and climbers.

The Madone Gen 8 features hoods that are narrower than the drops so you can adjust your positioning to prioritise aerodynamics or power. The two-piece design lets you quickly and easily dial in your fit.

The add-on RSL Aero Bottles and Cages were designed with Madone Full System Foil aero shapes to make the whole rider system even faster.

Features:

  • New light and fast aero tube shaping paired with light-yet-economical 500 Series OCLV Carbon makes this bike the lightest Madone SL Disc f/s ever and an ideal climbing bike.
  • Revolutionary new Full System Foil aero tube shapes improve airflow over the whole bike while maintaining the lightness that climbers crave. The bike’s entire rider system was meticulously designed and rigorously tested to be faster everywhere.
  • The race-focused comfort technology has been refined to be lighter and have nearly double the vertical compliance so you can ride stronger for longer.
