Chewed up nipples

[Jonny69]

If you take as many off as you can it normally leaves some slack in the remaining spokes, enough to poke them out the rim and get hold of them. When you put your new ones on, just make sure you use a bit of grease to stop them seizing. I'm surprised anyone ever thought it was a good idea to use aluminium nipples on a steel spoke - it's well known that steel and aluminium locks together.

Re:

Cheers Jonny ,

The reason for me doing them all in the first place is because I couldn't get wheel true with the alloy ones . I put a few brass ones in to true it up . Used wd40 on them , but they kept loosening. Using loctite on the new ones . Hopefully enough to keep them in place but still able to move them . Seems to have worked on the back wheel. Tried the front this morning about 6am before I went to work . Got the worse ones freed up at last , using mole grips and a screwdriver. Rim tapes turned up at work just now so itl'll be ready for the weekend

TBH, its usually easier to just unscrew all the ones you can and then when the wheel is all but completely dismantled, just use pliers on whats left and then rebuild the wheel with brass nipples.
You might find that the rear wheel either uses brass nipples anyway, either that or it gets the salty road grime washed off more often (either by the act of cleaning, or oil from the cassette and chain)
The only wheel i've ever had with conventional aluminium nipples, i rebuilt a couple of weeks after getting it. Cos i could.

Christ knows what'll happen if i ever need to true up my kysriums. Aluminium spoke threaded into an aluminium nipple threaded into an aluminium rim.

Oh, and if you rebuild it should remove the need for threadlock, thats *usually* the sign of a poor build. (Spoke prep is another matter altogether!)

Re:

I thought it best to keep the trueness in the wheel as much as I could and just do them one by one . Been building my own wheels for 20odd years now so I could have just taken them apart and start again but did it this way instead. Never used loctite on wheels before . Then again ive never bought a bike with factory built 20/24h bladed radial wheels either , with paired spokes and dodgy nips :evil:

The alloy ones seem to corrode on the inside where there is contact with the spoke. They look OK on the outside but then collapse at the turn of the key. Alloy nipples are horrid things demonstrating that weight weenies know nothing.

Except a weight weenie wouldn't use anything as heavy as a Bontrager Racelight, or use aluminium nipples on a daily wheel. Raceday only!

Re:

Maybe a good dump before the race (if youre that way inclined ) would be more effective . Lose overall weight more significantly and doesn't cost a penny !
