TrekMadone SL 6 105 Di2 Gen 8 Road Bike
The Trek Madone SL 6 105 Di2 Gen 8 Road Bike is a lightweight aero road bike that delivers high-end racing performance at a more accessible price. Crafted from OCLV 500 Carbon, it offers the aerodynamic advantages of the Madone SLR in a more affordable package.
It features a Shimano 105 Di2 2×12 electronic groupset for fast, precise shifting, along with alloy handlebars that help keep the overall cost down. Carbon wheels add to the lightweight performance, making this an excellent choice for riders who want cutting-edge speed and tech without the top-tier price tag.
