I'm putting the Trek 500 commuter back together and had a question. This has a 10 speed Campy Centaur compact (50-34 IIRC) and I run a 13-24 freewheel on it. It has a Shimano CN-HG93 chain. I was checking chain length on it, and from big-big, it looks like it has 6 extra links (not thru the RD).

This frame did not have dropout adjusters in it, and the wheel was always run all the way back in the dropouts (probably for tire clearance as the 700x32 Avocet Cross tires are tight). I put adjusters in, but don't have the wheel all the way forward. These are short dropouts also.

1) The rule of thumb is big-big +2 links?
2) If I remove 4 links then wind up having to put the wheel all the way back (w/o adjusters), I might be in trouble
3) Is this the type of chain that you need to replace pins if you end up having to reinstall a pair of links? Not well versed on these new fangled chains and stuff

I'm guessing it needs a minimum of 2 links removed, maybe 4?

Thanks!
