Carbon-Ti X-Lock EVO Rear Thru Axle

The Carbon-Ti X-Lock EVO Rear Thru Axle upgrades frames that use the X12 Syntace Standard with a lighter, precision aluminum axle. Carbon-Ti machines it from AL7075 aluminum and shapes it with variable wall thickness to reduce weight while maintaining stiffness. The axle installs and removes using a 6 mm hex key for secure and simple wheel changes. It comes in a 12 x 1.0 x 159 mm version for the Specialized Tarmac SL8 as well as other frames and a 12 x 1.0 x 166 mm version for Colnago and other compatible frames. Laser etched graphics and anodized color options complete this Italian made performance upgrade. See compatibility tab for more info.
