Onyx Torque Caps make the bond between your hub and Rock Shox fork dropout stronger with an increased surface area connecting the two. This creates a stronger, stiffer interface, giving you a more responsive front wheel with more control.
This product is only compatible with Onyx MTB 15x110mm 6-bolt disc mountain bike front hubs. It is not compatible with Onyx Centerlock front hubs (Onyx does not make a compatible torque cap axle for their Centerlock hubs).
