BTW- something no one mentioned. If you look at the cone faces you'll see that there's a raised collar around the axle. This is a secondary retention system that fits forks made for them. Instead of a plain U-shaped slot, the dropouts have a slot shaped like the old basketball court key.

The fork has to be spread slightly to install and remove the wheel. This feature may not be present in a fork not made for these hubs. The loss of the feature isn't as important as the fact that the collar will be too wide to sit properly in the dropouts, and will either jam, or shift sideways and cause the axle to bend.

So check the fit of the wheel into the fork, and if necessary use a rat tail file to prepare the dropout for the wheel.
