TREK DOMANE SLR 6 2020 [Review]

Trek Domane SLR 6 is a lightweight, high performance, road bike designed with a 700 series OCLV frame, hydraulic disc brakes, and Bontrager Aeolus pro 3V Carbon wheels with wide tires. Trek Domane SLR 6 also has internal cable routing and storage, which adds to the versatility of the bike. The carbon frame is light but strong, and it also features front and read IsoSpeed decoupler, which helps to smooth out rides. Its wheels and tires offer a fast and stable ride while its internal cable routing improves the look of the bike, and the storage enables you to carry enough supplies for your rides.


Front and Adjustable Rear IsoSpeed Decoupler

Trek Domane SLR 6 has a front and rear IsoSpeed, but the rear IsoSpeed can be adjusted. This feature, alongside its Bontrager tires and seat tube design, helps the bike to do well even on rough roads. The IsoSpeed decoupler also helps to increase the vertical compliance of the bike.

700 Series OCLV Carbon Frame

The OCLV frame offers a high-quality ride as it is light in weight, tough, and durable. The frame also features a DuoTrap S compatible, internal cable routing, storage, and fender mounts. All these increases the bike’s versatility, comfort, and efficiency.

Flat Mount Hydraulic Disc Brakes

These brakes allow the bike to work efficiently, even under unfavorable conditions. They provide a powerful and stable stop, and they are lighter and more efficient than mechanical disc brakes. With these disc brakes, the rider does not have to exert so much effort into controlling the bike. This way, the rider’s confidence is increased and can have a more fun ride.
