The Carbon-Ti X-Hub SP Boost Rear Disc Hub is engineered for high-performance Boost mountain and aggressive gravel applications where stiffness, engagement speed, and serviceability are critical. CNC-machined in Italy from 7075-T6 aluminum, the hub body and axle combine structural rigidity with low rotational mass.
The Boost 12×148 spacing increases flange separation for improved lateral stiffness in modern wide-rim wheel builds. A 4-pawl freehub mechanism engages a 56-tooth titanium drive ring, delivering rapid and consistent power transfer under load.
Carbon-Ti’s external, tool-less bearing preload adjustment allows precise micro-tuning without disassembly, improving long-term bearing performance and service intervals. The hub uses a Centerlock rotor interface and supports multiple freehub standards including Shimano/SRAM, SRAM XD, Shimano Micro Spline and Campagnolo N3W.
With a claimed weight of ~198g (variant dependent), the X-Hub SP Boost rear is positioned for premium cross-country, trail, and high-output gravel builds where reduced rotating mass and drivetrain response matter.
