Got a small twig caught in the chainrings earlier on the middle ring and stupidly rather than get off and remove it decided to shift upto big ring.
Yep chain snapped, first time I've had it happen. Its a SRAM 951 with powerlink.
I just wanted to get home so I didn't even check the chain out proper just put another powerlink in and got moving again.
Just had a look now and it was the powerlink that snapped ( I've put a bit of felt tip on the powerlink so I know I'm not counting it twice when spinning the cranks ) are these weaker than the rest of the chain or is it just coincidence ?
I've read about SRAM chains not being brilliant, but this is the first bit of trouble I've had in a couple of years of using them.
