Hey - recently picked up a used bike that had new wheels on them and noticed that the front hub appears loose on the axel. What I mean is that if the wheel is on the bike and skewer tight if I push the wheel (spokes or rim) the hub moves slightly on the axel. Not much, maybe a sixteen of an inch or less but it does move smoothly and evenly. My other bike (that has nicer wheels) does not do this and I don't know if this is a problem or just the way these are made. . .btw, the wheel spins fine and smoothly and is true.

Any thoughts?

Sheldon - thanks for the advice/link but I still have a problem. . .it appears that I need a special tool for one side of the wheel (Rolf Vector) because it is round and has slots in it (as though for a tool to hold it in place). So, one side has the typical square edge for a 17mm cone wrench but I need to grab the other side or else it just spins around. The LBS said that the did not have the tool (and looked surprised) and I can't find a tool at the Park site that looks like it will do the job.

Any ideas?

The slots are for a cone wrench. You just need the correct size.

None of the cone wrenches I see on Park Tool are round with teeth which is what is needed. One side will hold a standard cone wrench but the other is round with slots so a standard cone wrench won't grip - there is no square to grip.

It looks like this hub probably has cartridge bearings, and sometimes those can't be adjusted once they develop play. They're meant to be tossed and replaced once they develop a lot of play. If your skewer can't tighten enough to remove the play, then you might be looking at cartridge bearing replacement. As for that round nut with the slots, I don't know how to get that off, sorry!

Hard to tell from the photo but it looks like you need a "hook spanner" to loosen that nut. I agree, it's probably a cartridge bearing hub and "maintenance" consists of replacement.

Try to e-mail Rolf for information. Maybe Park tools can provide some guidance too.

Ok - there is a special tool! Just so happens that I did a quick search on ebay and found a Rolf Hub Tool for sale for 2.99. . .it arrived today and did the trick. I could not find the tool anywhere else new. . .

Thanks for all your help - photo attached.
