Wide Rides Better!

28mm wide external / 23mm internal rims suitable for 650b x 47–55mm (1.8–2.2”) tyres. The wider platform offers increased stability, stiffness and reliability allowing you to cover varied terrain smoother due to lowered tyre pressures making you ride faster.

Tubeless Ready

Yes, you can still run tubes, but we encourage you to try tubeless tyres and experience the confidence inspiring ‘free-speed’. Not to mention the extra traction, stability and smoothness.

Grav Al. wheelsets arrive tubeless-ready, with tubeless rim tape, valves and centre-lock rotor lockings. Simply install tubeless-ready tyres, sealant and inflate with a tubeless floor pump. Set up your Grav Al.s tubeless to help reduce pinch flats and punctures, decrease rolling resistance and increase control.

DT Swiss 350 hubs &
Sapim CX Sprint spokes

One of our favourite hub/spoke combination, the DT Swiss 350 CL Straight Pull hub and Sapim CX-Sprint Aero Bladed spoke. It's a fine example of a balance between weight, reliability and performance when paired with Curve rims. This combination has proven itself time and again under the harshest conditions and treatment we can throw at it.
