Factory thru axles compromise on weight, material integrity, and clamping consistency, leading to micro-play across the rear dropout during maximum-effort sprints and technical descents. The re-engineers this critical interface. Precision CNC-machined in Italy from aerospace-grade AL7075-T6 aluminum, it provides an uncompromising foundation that anchors your rear hub with surgical precision.
Engineered with variable-thickness butting, this axle pares away excess mass without yielding an ounce of torsional or bending stiffness. The conical interface seats flush against compatible Syntace X-12 standard dropouts, ensuring seamless alignment and eliminating disc rotor rub under heavy lateral loading. A cleanly recessed 6 mm hex interface enables swift, reliable torque application without the aerodynamic penalty or visual clutter of bulky quick-release levers.
Whether attacking brutal climbs on an S-Works Epic or dialing in race precision on a modern Colnago, this axle delivers uncompromising structural dependability. Finished with laser-etched laser graphics and rich anodization, it transforms an overlooked hardware element into a decisive lightweight performance upgrade.
