Carbon-Ti X-Lock EVO Front Thru Axle

The Carbon-Ti X-Lock EVO Front Thru Axle upgrades QR12 forks 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 117 mm version for the Specialized Tarmac SL8 as well as other compatible forks and a 12 x 1.5 x 117 mm Colnago-specific version. Laser etched graphics and anodized color options complete this Italian made performance upgrade. See compatibility tab for more info.
