frequency 7x hubs
At the core of CMR Light is WTB’s Frequency 7X hub platform, proven at the highest levels of racing with numerous race wins and an overall XCO World Cup title at the hands of Cannondale Factory Racing’s Luca Martin. Featuring a patent-pending hub/ratchet interface, these advanced hubs are engineered to handle demanding loads while delivering long-term performance and straightforward servicing.
DLC Ratchet Rings
All WTB ratchets use a DLC (Diamond-Like Carbon) coating to deliver greater hardness and significantly lower friction than traditional hard chrome-plated drive systems. To build on this durability, the inner (hub side) ratchet ring keys into place with splines rather than threads, allowing the hubs to withstand over twice the torque of traditional designs without requiring specialist tools for servicing.
Large & Durable Enduro Bearings
Frequency 7X hubs use larger than industry-typical Enduro bearings throughout, including durable freehub bearings that increase the load rating by up to 38% compared with competing rear hubs. This creates a stiffer axle assembly, improving reliability and reducing maintenance intervals. The hubs are fully sealed and rigorously tested to keep dirt and moisture out, making the Frequency 7X hubs ready for long days and demanding conditions.
Splined Inner Ring
To increase durability, the inner (hub side) ratchet ring keys into place with splines rather than threads, allowing the hubs to withstand over twice the torque of traditional designs without requiring specialist tools for servicing.
This robust design boasts a max torque capacity of 790nm, and can withstand 2.4x the load of threaded inner rings.
Carbon you can count on
CMR Light features a purpose-built, lightweight carbon rim engineered to deliver exceptional strength, stiffness, and impact resistance. Its 30mm internal width provides an optimized foundation for modern mountain bike tires, while a hookless rim design and wide upper legs help protect against pinch flats and support reliable tubeless performance. External spoke-hole reinforcement and 4D spoke drillings optimize load distribution and overall wheel strength.
Ride With Confidence
Whether it’s lightweight trail riding or all-out enduro, WTB backs its carbon rims with our Ride With Confidence Guarantee. If you break a WTB carbon rim while riding, as long as you’re the original owner, we’ll send you a replacement for free. No exceptions.
