I havin a new wheel built and i was gonna get a nipple key for it but the dude in the shop insisted on tryin to sell me a park one for £8 insisting antything else will round the nipple's. is it tru that all others are crap? i know halfords used to do some cheap last time i was in there.(years ago)
loz

I use a Spokey & it hasn't rounded the nipples yet.

any spoke key will work as long as its the right size for the spoke nipples' on your wheel
