This fast and tough wheelset for cross-country riding and racing follows on from our ever popular Gecko gravel/CX wheelset with a wider, stronger rim suited to XC tyres from 2.1″ and larger. The wheelset features our usual choice of hub options with centre-lock or 6-bolt disk mounts available as well as straight-pull or traditional J-bend spokes.
weights from 1300g/pair (650b) and 1366g/pair (29er).
Hubs are 6 pawl, 48 point engagement hubs with premium stainless bearings, 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 matt UD finish and no braking surface. Recommended tyre sizes are 2.2″ to 2.5″.
The wheels are finished with tubeless rim tape but valves are extra. A crash replacement scheme applies to all JRA carbon wheelsets.
