Which Chain? (Chains / Size / Width / Wear)

I hope you feel all warm and fuzzy inside having provided me with such an intelligent and witty retort to my clearly foolish question, you have certainly stamped your authority. Well done, have a gold star hombre.

The question was a good one. But it did'nt warrant a new thread.

Your chainset is 3/32, but your DA sprocket is, quite likely, 1/8". In which case you will need to go with a 1/8" chain.

Plenty of options, but for a decent quality at a decent price, I'd go with a KMC K710. Or the K710SL if you want to save a little weight.

There is 3/32 version of the DA sprocket though. If this is the one you have, I'd recomend going 3/32". This chain dinemsion is just as strong, but has a little more sideways flex. Making it more resiliant to less than perfect chainline.

You need to find out the thickness of your sprocket before making a decision.
