Built with a stout 19.5-millimeter internal tubeless EA90 SL rim that combines lateral stiffness and aerodynamics with a 27mm rim depth and Vault centerlock hub. With disc road cyclocross and gravel in mind the Vault hub was designed from the ground up to conquer anything from tarmac to sand traps. Larger bearings on a wider bearing stance and improved seals help to push durability to a new level. A reversed drive ring configuration gives 60 points of engagement at just 6-degrees for instant acceleration.
