Gecko strong carbon wheels

from £850.00 / pair

Our award-winning Gecko carbon wheels now have a high-strength option, the Gecko strong. Built with 28 spokes per wheel and a thicker carbon layup, there is no rider weight limit on these wheels. Suitable for road disk, gravel, cyclocross or cross-country MTB, weights start at 1398g (700c with straight-pull centerlock).


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 low weights, and are tubeless ready – supplied with tubeless tape fitted, valves available separately. The rims have a hookless bead for strength and impact resistance 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.
