i found this new/old chain from when i used to have a 9spd DH rig, and have no use for it if it isn't compatible. how long can this go on? if my only consideration is link thickness, and my drivetrain isn't new (so i'm guessing it's been worn in enough so that this slop is negligible), can i get away with this for the next 100 hrs or so (when i plan to replace everything anyway)? my setup is on a 36t/104bcd (no chaindrop pin, as i have an integrated chainguard). i can't imagine my 22t small ring comes into play...
