Overview
Wide Open Speed
The Waheela R was made for racing on rough gravel roads at top speed. The geometry was developed for command and confidence, the tubing was shaped for proven aerodynamics, and the carbon layup was crafted with the perfect balance of comfort and power transfer. Simply put: it’s build to rip.
Features
Aerodynamic Carbon Frame: Shaped tubing engineered specifically to reduce drag during fast gravel racing.
Wolf Tooth Tuning Chip: An adjustable rear dropout that lets you alter the wheelbase length and bottom bracket height to change how the bike handles.
Racing Geometry: A long top tube and short stem layout designed for high-speed stability on loose surfaces.
Massive Tire Clearance: Room for high-volume tires to maintain traction and mud clearance on technical trails.
Compliant Layup: A carbon construction tuned to absorb road buzz while keeping the bottom bracket stiff for efficient power transfer.
