Scott Speedster 20 Gravel Disc Adventure Bike 2017
Take the path less travelled with the Scott Speedster 20 Gravel Disc Adventure Bike 2017. Designed with a more stable, comfortable geometry to enhance off-road durability over longer distances, this bike uses a lightweight, strong frame, all whilst the carbon fork absorbs vibrations and remains rigid.
Laced to the brim with capable components, the Speedster Gravel 20 Disc is perfect for both on and off road adventures. Shimano’s BR-RS305 mechanical disc brakes keeps braking powerful and predictable, so when you do head off and the weather takes a turn, you’re never left on the descents without full confidence in your bike.
Shimano’s Tiagra 4700, 10-speed gearing is another area in which the Speedster exerts itself. This wide range of gearing and an 11-32t cassette gives enough spin to get you up those steep, demanding gradients, all whilst allowing you to turn down the power and sit back when your legs start to get tired.
Scott Syncros Race 22 Disc wheels and Schwalbe G-One Performance tyres work together efficiently, staying strong and giving immense grip, all whilst increasing puncture resistance. The wheels stay rigid when you’re heading up harsh climbs and sprinting out the saddle, too.
Features
- Strong, dependable and durable frame and fork combination allows for day-in, day-out riding
- Shimano BR-RS305 mechanical disc brakes provide powerful, reliable braking in a wide range of conditions
- Shimano Tiagra 4700, 10-speed gearing is perfect for spinning up climbs and powering along the flats
