Our road disk / gravel Gecko wheelsets just got much,much lighter with carbon rim options in 27.5" or 29er built onto our own JRA Centre-Lock disk hubs. Weights from 1280g for 650b or 1325g for 700c on our asymmetric, UD finish rims.
Where grip and light weight are your main priorities the Gecko carbon is the road-disk or gravel 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 650b or 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 matt UD finish and no braking surface. We recommend minimum 25c tyres, which in the case of Schwalbe Pro Ones will measure up at 28mm wide on these 21mm internal rims.
The wheels are finished with tubeless rim tape but you will need to order valves separately. A crash replacement scheme applies to all JRA carbon wheelsets - please click here > for more details.
