Oh, crap.

I'm a Clyde, putting heavy pressure on my chain each and every ride. I have rolled with SRAM chains for years; each and every one, until this last one, was first connected with a Powerlink (9-speed). Each and every one snapped in the first month, was chain-tooled back together -- and only the one I'm using now didn't run trouble-free for two years. (It's 6 months old.) WHERE the chains broke was random -- but never at the Powerlink. My theory is a flaw in the chain that shows up in that 'break-in' period.

Chains at Walmart, on their BSO's, get lighter use; IME, the only time there was a significant chain problem was during a recent recall, when ALL the chains on a certain model had to be replaced. I've worked with those things for over 12 years, and chains breaking is near the bottom of the trouble list.

As long as the pin is re-inserted to the correct depth, you can ride with confidence.
