Chain length and rear derailleur
On one of my road bikes I had to replace the chainrings (chain and cassette too), and for the smaller ring went with a 36. The old one was a 42 tooth. I have a short cage derailleur. But I can't get the chain length right. If I use the big ring-big cog method to determine chain length...it's too long even with the B adjustment screw to the extreme. Shifted to the small-small the chain rubs on the bottom of the derailleur cage. If I take a link out of the chain...then it's too short on the large-large combination...the chain almost binds in the derailleur. Is the 36 small ring really too small? Should I just leave the link in and let the chain rub on the derailleur? (although it rarely would because I wouldn't normally be on the small-small combination)
