Chain Rub
Hi everybody,
(Cross posted to Tandem board--Retro Grouch may have answered this already, but I already had it typed...)
I've been trying all day to make my chain stop rubbing. I'm new to this many gears, so my apologies for getting some of this terminology wrong. When I'm on the inner chainring in front (granny gear), the chain rubs the middle chainring (in front) when I'm on any of the smallest 2 or 3 cogs in back. I have the same problem when I'm on the middle chain ring in front (chain rubs the largest chain ring) and try to use the smallest cog in back. I hope that made sense. Is this a problem I should expect with 27 gears on a tandem, or is there something simple that I'm missing?
Thank you to everyone for creating such a great forum here. Has anybody else noticed that bikes have gotten more complicated in the last 15 years?
