Wondering if anyone has experience with these.

There's a used set at my LBS I can have relatively cheaply and I think they'd be a nice upgrade to the wheels on my 80's Peugeot.

My worry is servicing. I can regrease and true a conventional wheel but I'm not sure about these. The pair in question was set up for a single speed and the rear has a solid rear axle. One of the first things I'd like to do is convert it (back?) to a quick release.

Is it going to be much different than a normal hub? Should I just stay away from these things?

Thanks !
