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.
We recommend a minimum tyre width of 25c on these rims and a maximum pressure of 90psi with tubeless tyres, 70psi with tubes due to the hookless design.
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.
