Product Details

Trek Madone SL 5 105 Gen 8 Lightweight Aero Road Bike

The Trek Madone SL 5 105 Gen 8 Road Bike is a lightweight aero road bike that delivers race-ready performance at a more accessible price point. Built with Trek’s OCLV 500 Carbon, it shares much of the aerodynamic design of the premium SLR models, including refined tube shaping and a sleek silhouette.

A two-piece cockpit with hidden cable routing maintains a clean, streamlined look, while the Shimano 105 groupset provides reliable mechanical shifting. Alloy handlebars and wheels help keep the cost down without compromising everyday performance, making this an ideal choice for riders looking to step into high-speed aero riding with excellent value.

About Trek

The best bike, ridden everywhere.

Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.

Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
