Trek Madone SL6 - 2020, 58 cm

Trek Madone SL6 Road Bike — Size 58 | Carbon Aero Road Bike with Carbon Wheels

The Trek Madone SL6 is a fast, clean, and race-inspired aero road bike built for riders who want speed without sacrificing reliability or comfort. The full carbon aero frame and fork are designed to cut through the wind while maintaining excellent stiffness for powerful accelerations and efficient climbing. At around 18.9 lb, it strikes a great balance between aerodynamic performance and everyday rideability.

This bike is equipped with a Shimano Ultegra 2x11 groupset, known for its smooth, precise shifting and proven durability. Gearing is dialed with a 50/34 crankset and 11–28 cassette, making it ideal for fast flats, rolling terrain, and sustained climbs. Braking is handled by Shimano Ultegra, offering strong, predictable stopping power in all conditions.

Rolling stock is a standout feature here: Reynolds AR29c carbon wheels, tubeless-ready and aero-focused, paired with Continental GP 5000 25C tires for a fast yet comfortable ride. The cockpit includes Bontrager Elite aero handlebars (440mm), a 100mm stem, a carbon seatpost, and an Elves road saddle. Size 58 fits riders approximately 5’11” to 6’4”. With under 1,000 miles, this bike is pre-owned, in good mechanical condition, fully tuned, and 100% ride-ready.
