[Closed] Ggrhh. Why does my chain keep breaking?

spacemonkey · 2011-09-28T14:18:08Z

Sat: Two months old (as is cassette and rings) and broke twice on Sat while under med-high load. Plates seemed to be exploding outwards if anything. Also took the liberty of snapping the pin on my Park chain tool too. Mon: Same chain broke 3 times under med-high load within metres of each other, eventually taking the mech hanger with it. As before, plates kind of bending outwards. Wed: Fitted new chain and the fucking thing has gone again. Plates fine, but inner link somehow popped out without any distortion. Shimano HG93 for the record (XT mech and cassette). Really pissing me off now. Was supposed to be out this afternoon. Mate popped round Mon night and said he didn't see anything wrong either. Ggrhrhrhgrhrh!

KMC chains all the way for me.
Never had any issue with them and they tend to last far longer than the SRAM 991's I used before.

2.5mm get real -

Thanks for your opinion but if you don't mind I'll be ignoring any further technical input from you.
At least some of the Shimano 9 speed chains are directional, the instructions supplied with them definitely show which way a newly joined chain should travel. The instructions are bound to be online somewhere.
