The Profile Aegis Hub guards replace the existing cones on your Profile Mini and Totem Hubs
They are also compatible with the V.2 Madera Pilot Front and Cassette Rear hubs.
The Rear Aegis works with 3/8 or 14mm hubs. The Front Aegis is only compatible with 3/8 axles.
Remove the Axle bolt from the hub on the side you wish to install the hub guard (or on the non-drive side of rear hubs).
Remove the cone spacer from the hub.
Slide the Aegis into the place where the cone spacer was, and then re-insert the axle bolt. Put the wheel back on your bike, and go find something to grind.
If the cone spacer is “stuck” on the axle, the easiest way to remove it is to remove the axle from the hub. With the bolt about halfway threaded into the non-drive side of the hub, and your wheel out of your frame, and the drive side bolt and washer completely removed, hit the non-drive side bolt with a hammer until the drive side hub bearing and driver slide free of the hub. You should now have no problems removing the cone spacer.
Loosen and remove the axle nut and the non-drive side locknut. You will need to have two wrenches, or you can secure the drive side of the hub - use your axle nut and tighten the drive side onto the outside of your frame dropout.
Remove the cone spacer.
Slide the Aegis onto the axle. The hub guard takes the place of both the cone spacer and the lock nut. Re-install the wheel on your bicycle.
If the cone spacer is “stuck” on the axle, the easiest way to remove it is to remove the axle from the hub. With the non-drive side locknut removed from the hub and your wheel out of your frame, hit the non-drive side axle carefully with a plastic or rubber mallet or hammer until the drive side hub bearing and driver slide free of the hub. Take care not to damage the threads of the axle if you use a metal hammer - placing a small block of wood on the end of the axle and hitting it with the hammer is a great way to protect the axle. You should now have no problems removing the cone spacer.
