Then I have my Mandaric (14 speed) that I tinker with and tinker with and just can't get it right. Any big/big or small/small (even when not at extremes) causes some chain rub and I have to trim the FD going up and coming back down. I love the ride and don't really mind its quirks, I'm just trying to figure out if the issues are mine (not as mechanically inclined as I like to think) or if even the LBS would struggle to set it up to perform the way my Miyata does.
What's your experience?
I have two bikes that rub front small, rear small. The rub is on the inboard side of the big front chainring. I haven't tried messing around with spacers. When I posted a thread about it here a few months ago most replies were "why would you be in small/small anyway, learn how to shift." So last few rides I've just been getting used to shifting to the big ring sooner when shifting up.
