Description

Trek Madone SL 5 Gen 8 Road Bike For Sale

The Madone SL 5 Gen 8 is a lightweight aero road bike that offers top-tier race tech at a slightly more affordable price tag. It shares the same aero advantages as the more expensive Madone SLR Gen 8, but is built with a more affordable OCLV 500 Carbon layup and a two-piece cockpit with hidden cable routing. It’s a pure racer, with a geometry that lets you sprint at lightning speed yet stay in control on fast descents. A Shimano 105 groupset keeps the price tag reasonable while still providing you with reliable mechanical shifting.

Revolutionary Full System Foil aerodynamic tube shapes redefine the concept of speed and optimize aerodynamics around the entire bike
A slightly more affordable 500 Series OCLV Carbon frame and new tube shapes help to significantly reduce weight, making climbing much faster
With the robust Shimano 105 groupset you get smooth and precise shifting behavior for a pleasant price
The lightweight, race-ready IsoFlow comfort technology keeps you performing at the highest level for longer without compromising weight or air resistance
