8 speed chains compatible w. 9-speed cassettes...?

What issues, if any, would I encounter if I ran an 8-speed chain with a 9-speed cassette? Are the clearances too close to permit?

9 speed chains for 9 speed, there is a reason they sell separate chains, the 8 is too wide to work properly from everything I've seen.

Won't work. Chain plates too wide. Get the correct part before encountering FAIL.

Won't work. You'll find that the shifting will suck because the chain will constantly be trying to ride up on adjacent cogs. Been there done that.

Thanx for quick response! So it appears there are legit diffs 'tween diff speed drivetrains, and it's not all marketing hype. I'll stick w matching chains to drivetrains, and try to find tandem versions of the chain what will provide me w 2 lengths for cheaper than 2 separate chains.

chains are backwards compatible meaning a 10 speed chain would work on a 7 speed but not the other way around.

That's certainly true for rear shifting. For front shifting, the narrow chain may give problems with a front derailleur intended for a wider chain. It will shift but may require some fiddling.

Additionally due to strength issues, I would not replace a 9 speed chain on a 9 speed system with a 10 speed necklace, er, uh, I mean chain

Why do you think that a 10 speed chain is any weaker than a 9? The shorter pins on a 10 sp chain should make it stronger, at least in theory.

Theory? So is penis envy.
