Frame
Featuring a lightweight T800 Carbon Fibre layup and responsive and agile gravel geometry, the Free Ranger is a gravel bike designed to excel off road but remain fast and capable on the tarmac.

Specifically considered layup to ensure stiffness and compliance where required in different areas of the frame.
Groupset
Shimano’s GRX series has been designed for pure gravel performance, with optimised gear ratios, off-road handling, and precise shifting. RX810 represents the top tier of 11 speed mechanical shifting. Hydraulic brakes levers incorporate SERVO WAVE technology for unrivalled stopping power. An integrated clutch retention system provides chain security even on the roughest of terrain.
