Trek Madone SL 6 Gen 8 Road Bike In Crimson

Season:2025

Brand:Trek

Code:MadoneGen8Crimson

The Madone SL 6 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point.

It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. It's built to race with geometry that keeps you comfortable on the climbs and perched for the attack. A Shimano 105 Di2 electronic group set keeps the price down without sacrificing lightning-fast electronic shifting. Plus, it's topped off with carbon wheels for extra lightweight performance.

Features:
  • It's right for you if...You want a featherweight road race bike without top-end race pricing. You're up for racing, club rides or solo spins up winding canyons, and don't want to compromise between climbing efficiency and aerodynamics. You love the workhorse performance of Shimano's 105 group set, but want the added benefit of Di2 lightning-fast electronic shifting.
  • The tech you get - An ultra-light OCLV 500 Carbon frame with aero tubing and IsoFlow comfort technology. A 2x12 Shimano 105 Di2 electronic group set that delivers clean shifts thanks to trickle-down tech. Plus, it's topped off with Bontrager Aeolus Elite 35 carbon wheels that come set up tubeless.
  • The final word - The Madone SL 6 Gen 8 delivers race-worth aerodynamics and climb crushing weight. It's a bonafide superbike in a more economical package, thanks to its 500-Series OCLV Carbon lay-up and workhorse Di2 group set. It offers the same frame tech as its SLR sibling, like aero tube shaping and lightweight IsoFlow comfort tech, so you can stay at the front of the pack.
What is the difference between a road bicycle and a road race bicycle?A road bicycle bike is designed for general road riding, fitness, and endurance, while a road race bicycle is built for speed and performance, featuring a more aerodynamic frame and aggressive geometry. Are women's road bikes different from men's road bikes?Womens' road bikes often have a slightly shorter top tube, narrower handlebars, and women-specific saddles to improve comfort and fit. However, both men’s road bikes and women’s models share the same core technology. What should I look for in a carbon road bike?A carbon road bike offers a lightweight frame with excellent stiffness for improved speed and efficiency. When choosing one, consider factors like frame geometry, groupset quality, and wheel compatibility to match your riding style.
