Where grip and light weight are your main priorities the Gecko carbon is the road-disk, gravel or cyclocross wheelset for you. With an internal width of 21mm the only limit is your frame clearance. We recommend a minimum tyre width of 25c on these rims and a maximum pressure of 80psi.
Hubs are 6 pawl, 48 point engagement hubs with premium stainless bearings.
Built onto our carbon Gecko rims in 700c. Rims are tubeless ready – supplied with tubeless tape fitted, valves available separately. The rims have a hookless bead for strength which means tyres should be inflated to a maximum pressure of 80psi. The rims have a matt UD finish with grey transfer Gecko decals, and no braking surface.
The wheels are finished with tubeless rim tape but valves are extra. A crash replacement scheme applies to all JRA carbon wheelsets.
