CNC machined from Delrin (a really strong and durable plastic).

Only compatible with Profile Mini and Elite front hubs as well as Madera Pilot front hubs.

Requires the knurled cones that come with newer Profile front hubs. Will NOT work with the older style, all-aluminum front hub cones.

You can buy an adaptable cone with the guard if you have the old style.

The hub guard slides over the hub cone. It will sit snug against your fork and hub cone when the wheel  is tightened down.
