[Closed] Alloy nips - when one breaks will they all follow suit?

Had a good start to the ride earlier, out the car park and notice a rubbing on the front, have a spoke hanging out of its hole. Spoke is fine, nip had sheared.

Gonna struggle to get to the LBS to sort this before HONC next weekend - will the rest self destruct imminently resulting in my painful death? The wheel was OK today, having driven 2 hours I wasn't about to sack it off so put 40k on it around the peaks but it was looking a bit wobbly when I got back...

Is it also really stupid of me to want to whip a nipple off another wheel and bung the same spoke back in? it looks a little bit bent but only where it crosses over the others.

Wheels are 6 months/1000k old so would have hoped aluminium fatigue wouldn't be an issue yet?

I've replaced alloy nips with brass out of a wrecked wheel no problem.
Though once four or five had gone it was time for a full rebuild.

Mates Spesh did this on a weekly basis, so I gave him some brass ones to replace the lot. I guess they corrode at the same rate. For the sake of 60 grammes or whatever, he doesn't have to listen out for the twang and tinkle noises now.

If the nipple has sheared it normally means the spike is marginally too short. The rest will break. Replace them all with brass and it should be fine. You'll probably be ok for a while with just the one replaced.

Once one went on mine, they all started to go. Managed to break 2 on a ride home along a sustrans cycle route. Got the whole wheel rebuilt.

I lost three a few weeks back on the front wheel while riding. Replaced them with better (but not brass) ones i had from a spare wheel. [i]All good[/i] i thought - then as i was heading out the following week i did the [i]ride the bike to the car test[/i] and when i pulled a stoppie, half a dozen more went and the wheel folded. It's in getting properly fixed now.

Yeah, happened to one of my wheels but it took quite a while. It wasn't a sudden thing...

In my case it was due to corrosion.

So when I asked if they'd all go, I was referring to [b]one[/b] wheelset....
Not the other wheelset on the road bike, which went ping as it let go of a spoke earlier - that's 2 rides this weekend and 2 roadside wheel truing sessions!

Cannondaleking - cheers but up in the west mids! ๐Ÿ™‚

Ive had brass ones go like this before. Caused by an over tensioned wheel tho.

Yes, sometimes you fit a new one and some go pop when you are just truing the wheel before it ever leaves the stand.
