In-stock Gecko carbon wheels – 28 hole only

£864.00 / pair

In-stock and ready to go Gecko carbon wheels – light and strong versions built on the popular straight-pull hubs. The same as our custom-built wheels but ready to send in 1-2 days.


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 asymmetric for maximum strength and stiffness at very low weights, and 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. As all tyres come up wide on these rims 80psi is plenty, for example a 25c Schwalbe Pro Ones tubeless will measure up at 28mm wide. 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.
