I found a couple of broken nipples on my girlfriend's mountain bike, last time we were preparing to go for a ride. Aluminum nipples, stock machine-built wheels.
I've used aluminum nipples on some of the wheels I've built, but since I was hand-building I could ensure that they were properly tensioned; So far no problems.
Def aluminum nipple, tension was good (AFAIK - I do check them periodically as I'm on the larger side, so last time was prob a month ago
I was out riding this weekend so I have only just got round to looking at this.
This is what I found :
So the rim is cracked. Bike is about 2 years old and I have Mavics on my other bike that have been fine so not sure what happened here. Is this a warranty job do you think ? No idea how long rims are warrantied if at all
