The Carbon-Ti X-Hub SP Centerlock Hubset combines the brand’s precision Italian machining with modern straight-pull geometry for an exceptionally lightweight, durable, and serviceable hub platform for high-performance disc-brake wheel builds.
The rear hub utilizes a 7075-T6 alloy shell, 4-pawl driver, and a 56-tooth engagement ring for rapid, consistent pickup. Bearing preload is managed through a tool-less external adjustment ring on both hubs, allowing immediate fine-tuning during wheel service.
The front hub (92g) is available in 12 × 100 or 15 × 100 options; the rear hub (approx. 189g) is 12 × 142 with multiple freehub options including Shimano / SRAM 11-speed, SRAM XDR, Campagnolo N3W and Shimano MicroSpline.
This hubset provides optimized flange geometry, a centerlock disc interface, and straight-pull spoke holes — ideal for stiffness-focused, weight-conscious wheel builders across road, gravel, and cyclocross disciplines.
