Carbon-Ti X-Hub SP Boost Front Disc Hub


As an offshoot of exotic materials manufacturer LLS Titanium, Italy based Carbon-Ti draws from decades of material science and design experience to bring the cycling community an array of quality components. Since 2005, Carbon-Ti has produced uniquely handsome parts that make no compromises in either weight or performance.

The new Carbon-Ti Straight Pull Boost X-Hubs represent the continued refinement of Carbon-Ti cycling products.  Carbon-Ti manufactures this hub from a solid block of Al7075-T6 aluminum, which is meticulously CNC machined to achieve an incredibly light weight while maintaining an impressive stiffness-to-weight ratio.  The 17mm axle, also made of Al7075-T6 aluminum, has a variable wall thickness to keep the weight low while retaining strength in higher stress areas.  This axle rides on two high-quality sealed bearings, with externally adjustable preload courtesy of Carbon-Ti's Bearing Preload System Tuning (BPS).  This preload system, which consists of a machined dial and grub screw, makes hub adjustments quick and easy.  These 110mm boost hubs come in at a very impressive 95 grams and are 100% made in Italy.  With the combination of its light weight and robust build, Carbon-Ti's X-Hub SP Boost hubs should be at the top of the list for gram-conscious riders who push their components to the limit.
