Aero Drive-Wheel

650c, Aero Carbon Drive-Wheel

Aero carbon drivewheel uses a 50mm deep rim to maximize aerodynamics.

Available in both TUBULAR and CLINCHER configurations.

Each wheel is handbuilt with matched spoke tensions using a tensionmeter.

The brake track is typically the "Achilles Heel" of a carbon rim due to heat build up (why carbon rims initially had aluminum brake tracks). This is especially a concern with handcycles due to all the braking energy being absorb by one rim (rather than two on a bicycle). Although more expensive, in order to guard against rim failure, during rim construction, C7 Concepts uses the highest temperature resin available.
