I bought a pair of wheels from ebay fairly cheap, rebuilt mavic classic pro hubs onto FIR 120 rims. The spokes used were straight-pull as per the original build with alloy nipples.

However upon recieving the wheels and riding them I have found that whoever did the rebuild hasn't put enough tension in the spokes and loctited them!!!!!

I dont know what grade they used on the wheels, but is there anyway to get the nipples moving freely again.

I took them to my LBS to have a look at but they said that because they have been loctited they are pretty much unworkable.(Mind the LBS is run by muppets). Anyone else have any ideas without a complete rebuild?

Heat. Try to localize it as much as possible. Meaning, use a high capacity focused heat source that will warm up the nipples quickly. A small butane torch will work well. Unless the builder used high temp threadlocker, you only have to heat things up to 140-180F.

You will need to completely remove each spoke from each nipple, replace each nipple, and steel-wool the threads of each spoke.

What color is the loctite? Red or purple should break with just some torque. If they used green, you're screwed....

After advised to do so by some wheel-building expert wannabe, I used blue loctite when truing up my wheels. I'm now thinking that this was not a very smart thing to do. I'm using brass nipples, so I think I can exert more torque than if they were aluminum alloy. However, I am also interested in what to do. Would a hair drier work?

no its blue. Unfortunately because the spoke are radial some of them are just rotating when you use a spoke key on them.
Does heating them disolve the loctite or just give you enough time to tension the spokes?
Also I thought that there was a remover you could buy?

Heat will melt the threadlocker, but it will harden up again after it cools off. You can however melt it and place a drop of thin oil on the threads. That would weaken the threadlocker bond enough to allow for regular adjustment in the future.

Yes, I think Loctite started selling a remover a couple of years ago. I'm not sure how effective it is though.

A hair drier may work, but it will cause a large area of your wheel to be heated up. I've never tried it. I'd be afraid that it may cause permanent deformation of the rim due to the tension in a wheel....maybe I'm just being overly cautious here. If you have a relatively large capacity soldering iron, you could try using that as well to heat the nipples.
