Description
Trek Madone SL 5 105 Gen 8 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.
