Powerlink failure

tcmedara said:

As I was doing a bit of maintenance on the FS ride this afternoon, I noticed
a clicking sound associated with the chain passing over the rings. Upon
closer examination I noticed one of the sideplates on the 9sp powerlink was
horribly bent. I tried several means to remove it, but ended up having to
pop a pin and install a new chain.

You should have just taken it to the LBS, they'd have probably done it for
free :^D

I distinctly remember a bizarre episode of chain suck last weekend.
This is a rare occurance and is usually a sign that it's time to lube
up again. I'm wondering if the chainsuck episode was a result of the
bent sideplate or was the cause. The powerlink was the only damaged
link on the chain so I suspect that it failed first and caused the
chainsuck problem. Either that or it's just coincidence that the
powerlink was the one part of the chain that took the brunt of the
abuse.

I've been using SRAM chains w/ the powerlink for years and never had
one fail before. Any similar experiences or comments?

I had one of those snap in replacement chain links go on me a while back.
Can't remember the make, whatever Halfords sell (only bike shop open on a
Sunday).

Yes. One failed on me uncatastrophically, and I ended up reusing it. Until
it fell off again going down some stairs. I put it back on. Fell off
again, this time in gravel. Found it - put it back on. Fell off again.
Found it and promptly went home.

My roommate's PC-69 just plain snapped on him on a random link. He weighs
170 and wasn't really cranking it...

I thought about it, but I didn't want to risk it. It may have sent Scottie
'round the bend even further. I settled for my 5% Club member discount.

You are the second person I've ever heard with a problem with them. Still,
it's a "Weakest Link" kinda thing.

Personally, I've always rivetted my chains, and I use mostly SRAM PC-58s
(despite the instructions saying you can't do this, it works perfectly.)

The only chain I've ever broken was a Sachs M-41(ancestor of the SRAM PC-48)
on my Tandem that I pushed past its useful life. Ended up
pushing/scootering the thing 9 miles home.
