Good point Scamper - since going HammerSchmidt and 1*9 I'm seeing less chain wear than when I ran a front mech.
Chain Wear - how often do you change yours?
Come to think of it, so am I.
I've worn a new cassette to knackered slippage whilst changing chains at 0.75. I put a brand new XTR 8 speed cassette on the tandem then rode 4000m on it changing the drive chain 3 times when 0.75 was indicated. During the life of the last chain, it started to skip on the most used sprockets. So that's with good chains and a good cassette.
Shame you can't change sprokets anymore, I could have easily got 8000 miles out of the rest as it wasn't really worn.
If you are relying on the Park Tools CC-2,
then I think you are changing chains far too frequently.
Park CC-2s are a bit rubbish in my humble opinion. The solid plate chain checkers don't have anything to go wrong, sloppy or bent like the cc-2 has.
I run cheap chains and will swap 3 or 4 over so they wear together. That way, if one gets mangled, then there's still a couple of spares which will match to the cassette. When the chainrings start sucking it's time to start thinking about replacing the whole lot together. Sometimes just switching to one chain and running it to death will stop the cahinsuck too..
It's no drama to swish the chain in the sink, stick it on the radiator and chuck the next one on the bike when it's dry. It's a no-brainer when it comes to cost IMO. SRAM 951s can be had for about 6 or 7 quid each.. A 990 or xt cassette plus a couple of decent chainrings is going to be at least a ton.
This may be one of those myths, but I've heard there's about a 5% efficiency difference between new and worn drivetrains, so doing this means you're spending much more time on a newish chain.
To be honest it depends on your groupset. Yes you could run your chain into the ground until it falls to pieces and up to that point it will work seamlessly but beware the next chain you fit will skip and miss beats all over the place due to the wear on the cassette/chainrings/jockey wheels. If your running X5/X7 then cost of replacement isn't too bad. I'm running XTR on one and XX on another and the cost of replacement is ridiculous! I think i'll change my chain for £30 instead of trashing £1000 groupset!

Why the thread resurrection?
