Race Alloy Hubs deliver low drag, high reliability, and excellent sealing from the elements. They're meticulously optimized for strength-to-weight ratio, meaning exceptional gravity durability without a hefty weight penalty. Flange angles and spoke hole designs have been improved for precise spoke/nipple alignment, reduced spoke hole stress, and increased wheel longevity. New Alloy Seal Shields on all freehubs enhance durability and protection from the elements. 

Our proven 60-tooth ratchet and pawl system has been refined over the last decade. The 60T ratchet ring tests exceptionally strong and durable, with teeth of sufficient size to ensure flawless engagement and long wear life. 3-Pawl / 6° freehubs provide 60 POE or a relatively low 6° engagement and high levels of reliability in high torque and heavy impact environments. It also minimizes pedal kickback which is more pronounced in bikes over 150mm travel, especially during high-speed descents on rough terrain. 4-pawl / 3-degree freehubs are cross-compatible and available separately for those that prioritize quick engagement and pedaling efficiency. 

• Boost and Super Boost rear hubs feature e*thirteen's proprietary "Floating Thread Alloy Axle System", which minimizes preload drag and allows for easy tool-free service. Steel axle kits are also available separately for those particularly hard on hubs. e*spec and DH hubs utilize steel axles to withstand the rigors of heavier, higher torque, gravity disciplines.
