WELCOME TO THE C7 CONCEPTS ONLINE STORE

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.


  • Built with high quality Sapium or Pillar spokes and self-locking alloy nipples


  • The production version is pictured with the C7 SL hub, but is available in a variety of hub and spoke configurations.
