Wheel development

Development of high-quality parts

The tyre pressure control system is integrated into each hub of a wheelset. Apart from a somewhat bigger hub diameter, the appearance remains similar to a normal wheel. We focus on lightweight, durable, and compliant wheels. We make use of light carbon fiber reinforced rims for which we made the design of the rims ourselves in close collaboration with our rim manufacturers: an optimal design with a good balance between weight, stiffness/strength, and riding experience. Our GX-30 and XC-28 wheels use different rims, which fit their application best:

GRAVAA GX-30 wheels compose of asymmetric 30 mm high rims with an inner width of 25 mm. The rims have a spoke offset of 2.5 mm.
GRAVAA XC-28 wheels compose of asymmetric 28 mm high rims. These rims are available with an inner width of 25 mm or 30 mm. The spoke offset is 2.5 mm.

All our carbon rims are made with advanced carbon fiber technology. We guarantee the highest precision, lightweight, and strong rims. All our rims undergo extensive testing, supported by recognized external wheel testing institutes, to provide us with rims of highest quality.

For the freehub system, we developed a 6-pawl system with a narrow engagement angle. The design is specifically made to fit best to our hub, and is compliant with the cassettes of all major brands.
