SRAM Mountain vs Road chains
I have a SRAM PC-99 chain, which is a mountain chain, I think. Before I install it on my road bike, can anyone tell me if there is any significant difference between that and a comparable road-specific chain?
Thanks.
Thanks.

Thanks. I thought mountain chains might be beefier, the way certain 1/8" BMX and track chains are supposedly stronger than 3/32" chains... But that's another debate.

I wish roadbikereview.com and mtbr.com would post reviews of the same chain. Right now their reviews almost never overlap, so when I see a bad review of a chain on mtbr I can't compare it to a review by a roadie,so I don't know if it is because the chain is poor quality or because mountain bikers tend to abuse their chains more than the roadies...
I just went from a KMC-9000 9 speed on my roadie to a SRAM PC-951. Both chains have awful scores on mtbr, but the KMC has held up fine for me.

Since I don't recommend nor generally sell Shimano chains, this has never been an issue for me. The Sram chains I use and recommend work fine with either HG or IG sprockets.

I just want to elaborate on what Sheldon is saying: If there were any actual difference between most road and mtn group chains, IE outer plate thickness, and roller/pin width, then the spacing of the two groups and shifter pull of each would be different. So almost none of it would be compatible. And now almost everything is. Any incompatibility issues I have encountered have almost been on Sram components where the pull ratio differs in a few shifters to cog sets...
