Trek Domane SL7 - 2021, 50 cm

2021 Trek Domane SL 7 — Size 50 | Carbon Road Bike | Carbon Wheels | SRAM Force AXS

The Trek Domane SL 7 is a comfort-focused endurance road bike that still knows how to move fast. Built around Trek’s proven carbon frame with IsoSpeed technology, it smooths out rough pavement, long rides, and broken roads without sacrificing efficiency or responsiveness. This makes it an ideal choice for long-distance rides, gran fondos, endurance racing, or riders who want speed with real-world comfort.

This bike is equipped with a SRAM Force AXS 2x12 electronic drivetrain, offering crisp, wireless shifting and a wide gear range thanks to the 10–36 cassette and 46/33 chainrings with integrated power meter. Braking is handled by SRAM Force hydraulic disc brakes, delivering consistent, confident stopping power in all conditions.

Rolling on Bontrager Aeolus Pro 3V carbon wheels, the Domane feels stable, smooth, and fast, especially paired with 32C tires that add extra comfort and control. The setup is tubeless ready, and the cockpit features Bontrager Elite handlebars, a Ritchey adjustable 90mm stem, and a Bontrager carbon seatpost for easy fit fine-tuning. Size 50, best suited for riders approximately 5’2” to 5’6”.

This bike has around 2000 miles, is pre-owned, mechanically excellent, fully tuned, and 100% ready to ride. As expected from a bike that’s been properly ridden, there are some cosmetic marks from normal road use, visible in the photos.
