GRAVAA
VONHAND - Gravaa Pressure Control Laufradsatz
Gravaa hubs allow you to control the tire pressure from the cockpit. More air pressure on the asphalt, less on the corrugated sheet track or on the cobblestone. More in the dynamic finish sprint, less in the steady pursuit over rough gravel. And quite lazily, it even replaces the bicycle pump, because the hubs, as soon as the impeller rotates, checks the tire pressure and adjusts it to the preset value. You can find out how this works in detail in an interview with Co-CEO John Zopfi in our VELOZETTE.
As one of only two wheel manufacturers in Europe, we prefer to install the hubs for VONHAND wheels with the Discus 40/45 LTD rims from 3T or the G23 from ENVE. The Discus 40/45 LTD impress with their benchmark-setting width of 29mm inside and the aerodynamic shape with a rim height of 45mm. The G23 are known for their unbeatable robustness and comfort even in rough terrain.
For all those who want to use this system even on bad roads, are planning to participate in Paris-Roubaix or just want a wheelset for asphalt and gravel, we recommend the ENVE SES 3.4.
Attention: The system is not tubeless-ready yet. If you buy a free upgrade in spring 2026. Photos of the wheel sets do not show products with Gravaa hubs!
