I've been happily riding my recently overhauled Peloton (here: http://www.bikeforums.net/showthread...fore-amp-After), but it has an issue that's driving me mad. I can't seem to take the slop out of the chain and it's constantly smacking the chainstay when I stop pedaling. I've read all over on how to get the chain length correct. I've got it just barely long enough to go into the large/large combination, and that's not a smooth shift at all. It really should have one more link in it to prevent damage to the rear derailleur.
So what's left to do? I could shorten the chain, but then I won't be able to use all my gears. The front is a 53/42 and the rear is a 13-21. Rear derailleur is a Superbe Pro and the spring seems to be plenty tight. What else could it be? The freewheel was NOS and spins very freely. I'm out of ideas and since this doesn't happen on any of my other similarly equipped road bikes, I refuse to just "deal with it."
Any insight from anyone? By the way, this obviously happens most notably on the 42T ring up front and basically any gear on the back. Thanks a ton in advance for any insight.
