Trek Madone SL 5 Gen 8 Road Bike in Matte Cobalt Blue/Trek Black/Living Coral

Season:2027

Brand:Trek

Code:57653BLU

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 500 Series OCLV Carbon lay-up and two-piece cockpit with hidden cable routing. A Shimano 105 groupset, alloy handlebars, and alloy wheels keep the price down while still delivering clean mechanical shifting.

Features:

  • Trek's lightest Madone SL Disc ever, featuring 500 Series OCLV Carbon.
  • Full System Foil aero tube shapes improve airflow while maintaining lightness.
  • 80% more vertically compliant IsoFlow technology for increased comfort.
  • Adjustable aero cockpit with hoods that are narrower than the drops to prioritise aerodynamics or power.
  • Rooted in racing, informed by feedback from Lidl-Trek's fastest sprinters and climbers.
  • Compatible with add-on RSL aero bottles and cages designed with Full System Foil shapes.
  • Shimano 105 groupset provides reliable mechanical shifting.
