Featuring Infinity hubs, ID360 freewheel and Maxtal welded rims, this modern XC wheel lives up to the legendary Crossmax name: strong, reliable, and tubeless ready. The name Crossmax has a long history in the world of XC riding and racing and this new wheelset lives up to its name with many of the same features and technologies as pro-level XC race wheels, but at a far more attainable price. One of the key factors is our UST technology, which allows for easy setup of tubeless ready tires and gives you all the associated benefits including better traction and control, a smoother ride quality and a reduced risk of punctures. The rim is welded for added reliability and features a 25mm internal width with a hookless profile. The Infinity lighter hub design optimizes lateral stiffness and spokes tension. Our Instant Drive 360 freewheel with a double ratchet system provides fast engagement and top-level reliability. The rear hub is compatible with Shimano HG9, Micro Spline and SRAM XD driver bodies. The Crossmax is available in 29'', with 6-bolt or center lock brake rotors and Boost axles (15x110 front and 12x148 rear) or standard axles (15x100 front and 12x142 rear). It is also available in 27.5'' with 6-bolt or center lock brake rotors and Boost axles (15x110 front and 12x148 rear), and 6-bolt rotor with standard axles (15x100 front and 12x142 rear).
