Exceptionally Strong and Lightweight
The Avalanche Sport 29 is built on an exceptionally strong and lightweight 6061-T6 Aluminium frame. Providing stiff, responsive and lively riding characteristics. The frame follows the GT Avalanche tradition and features the iconic Triple Triangle construction for superb strength and comfort. To add additional control to the already awesomely responsive design when the terrain becomes demanding is the SR Suntour XCT-HLO suspension fork. Equipped with a Shimano 3x9-Speed drivetrain that supplies superb pedalling efficiency, combined with smooth and crisp shifting, and excellent reliability.
Efficiency and Rolling Performance
This Sport model is all about efficiency and this is achieved by the combination of All Terra hubs and the All Terra Double Wall rims. This wheelset provides reliable and fast rolling performance regardless of the terrain you ride on. To maintain your speed and to ensure you have grip and traction at all times, this bike is equipped with the All Terra Cypher tyres. This wheel and tyre combination, when used in unison with the exceptional Shimano M315 brakes, make any trail session and fun and memorable experience.
