Here's one...muncher

Just got a new rear for my beater/commuter (MTB). XT hub, phat rim. First ride out - get a "ting" noice once per revolution, sounds like something catching a spoke. Check - nothing in the wheel etc. Take wheel out and spin - same noise. Can't be bothered to strip the wheel, so it's going back to the LBS for them to sort it out. Can only think it's a cracked ball-bearing or a crack in the shell of the hub causing a vibration from the hub outwards. Any thoughts/experience of similar?

Tks - M.

Most likely it is something simple, like your rear der. cage hitting the spoke OR the little metal slug that is used to join the ends of the rim together coming loose. This started happening on my MTB w/517's. Could also be related to the crank arm(s). Not too unusual for a spoke with low tension loading/unloading.

The list goes on - you'll need to play detective to figure it out, then make little experiments to verify. Little repetitive noises drive me nuts.

Neither do I. Though that you might have hit it with the spoke idea - taped them together in pairs till I found it stopped, then just tweaked with a key a fraction, and hey presto! Gone. There is always something new to learn.....

Tks for the help - M.

I had a similar thing once...tore everything apart looking for it, it would come and go, drove me crazy.
Turned out to be the tip of my shoelace tinging against the crankarm when my foot came around, but only when I'd tied the shoes with a certain amount of free end sticking out.
Good one!muncher

Bet I can guess how happy you were when you figured that one out amoungst the pile of bits of wheel. Thought that sort of thing only happened to me....
