i got 3 months out of a 10 spd DA chain before it started skipping.
replaced it with the superlight sram chain, because it was the only one in stock at the lbs (which costs a ridiculous amount of cash - 70$
that was in early august. rode the bike through the 1st week of october, then put it away. started using it again on the last weekend of March.
Have put in a LOT of hours since then and still no probs (but most likely i'll be putting a new chain on it next Monday).
it'll be a DA chain, but that's only because i have one kickig around.
