Trek Madone SL 6 Gen 8 road bike
Brand: TREK
Reference: 5319972
Description
Trek's 2025 Madone SL 6 Gen 8 is a lightweight, aerodynamic road bike that offers elite racing technology at a more affordable price. It offers similar aerodynamic benefits to the higher-priced Madone SLR Gen 8, but with a cheaper OCLV 500 carbon layup and a two-piece cockpit with hidden wiring. It is designed for competition, with a geometry that keeps you comfortable on climbs and ready to attack. The Shimano 105 Di2 electronic group has an affordable price, although it still incorporates a devilishly fast electronic change. And, to all of the above, we must add extremely light carbon wheels that allow you to obtain maximum performance.
Details
It is ideal for you if...
You want a featherweight road bike, without the price of a high-end competition bike. You enjoy racing, group rides or solo kilometers through winding gorges, and you don't want to give up climbing efficiency or aerodynamics. You love the performance offered by the Shimano 105 groupset, but you're also looking for the added benefit of fast-paced Di2 electronic shifting.
Features
The revolutionary tube shapes Full System Foil aerodynamics redefine the aspect of speed and help optimize the aerodynamics of the entire bike.
The more economical 500 Series OCLV carbon frame and new tube shape reduce weight where it matters most to help you fly up the climbs.
Carbon wheels keep weight under control and increase performance, so you can crush the climbs and descend the open grave.
The changes are tremendously fast and precise, thanks to Shimano's Di2 technology applied to the 105 group.
Lightweight, competition-oriented IsoFlow comfort technology helps you ride with more power and for longer, without sacrificing weight or aerodynamics.
This bike comes tubeless equipped, a first in Trek's road performance history.
