Can the axle be removed from track hubs? I have basic Formula track hubs.

The goal here is a locking skewer, just curious if that's possible with this hub. I don't think it is, but I thought I'd check as it would be the most convenient locking option here.

track hubs are no different than road hubs. If you have the sealed bearing formulas though you'll need to work something out for the bearings to seat on. There have been threads about it.
