noise coming from my rear hub

Do you have a rubber boot covering the non-drive side bearings? Sort of cone shaped? If so, like on one of mine it might need a little love. Some lightweight oil of some grease. Carl

Unsure but thanks for the tip. I'll check it out.

Carl's got a good suggestion. If lubing doesn't work, try seal removal. Back when I was on the road with a pro women's team in 2007, I had to remove all the rubber dust seals from the drive side of their wheels because of dragging/squeaking/etc. I had to keep a constant eye on any excess dirt/grime being collected in the freehub area, but it didn't annoy them for 3+ hours at a time, so it was worth removing it.

To be on the safe side, I'd take the bike to an LBS that you trust and get them to have a look, as well. They may not even charge you for the estimate. If they've got the answer, then you can either get them to do it, or you can attempt to do the repair yourself (if that's the case, it's probably a wise decision to leave them a tip or deliver them a six-pack for their trouble... it'll get you a long way with shop guys!) It's extremely hard to properly diagnose on a forum. If I could only get my hands on it...

Forgot to ask... what brand/model of wheels?

Thanks Josh. Yeah I understand it's tough to diagnose such a thing via a forum. Checked out Carl's tip but there's no rubber boot. They're Neuvation rims...M20s I think and look to be fairly sealed, i.e. nothing noticeable to be lubed. They're great for the most part; plenty of rough roads and true as the day I installed them. I'll take it to my LBS; I've got new brakes and front derailleur that I need to have installed so I'll have them check it out for me. Thanks again.

I've had to do new bearings on some Neuvations before. They're pretty simple to do... not the most intricate hub design. May have something to do with it. Call up Neuvation if that's the case. I've seen them send out new bearings on the house in certain situations, if that's the issue.

Thanks Josh, had a feeling it might be the bearings. Don't know much about mechanics but that seemed the most likely culprit. One last question; is it going to screw up anything if I keep riding until I get the bearings replaced?
Thanks again,
Harold

It will probably make you more mad than anything from the constant noise. It'll drag a little, but it shouldn't mess up too much. If it's frozen, there's a possibility it could scar the axle a little, but it shouldn't be to that point yet. I'd still work on replacing them as soon as possible.
