Stripped another one. What did they make these things out of, cheese?

Luckily I picked up one more than I needed, so I should be set for commuting as long as they're tight enough at the moment. If the wheels slips and I have to reset my chain tension my hopes won't be high.

I'm giving up on these old nuts. I'm gonna find some way of ordering new, unused ones before I exhaust this town's supply.
