These fit our 6-bolt Boost 110mm spacing 6-bolt front hubs. They will not fit any other brand of hubs! They also do not fit our Centerlock disk mount Boost hubs.
Available in standard 15x110mm or Rockshox Torque Cap (30mm outer diameter) versions.
If you have a Rockshox fork, most newer models will be Torque Cap compatible. There is a small decal low down on the fork leg confirming Torque Cap compatibility.
