Sometimes you can run into it when trying to use an 8 speed shifter with a 7 speed cogset, or vice versa.
So I guess I have no useful advice.
Not that unusual.
I appreciate your thoughts, I really do. I appreciate the time everyone has put into this thread for me. I don't understand how the frame alignment issue could be so problematic either, but we've ruled out almost everything else except for the shifters - so the mechanic dude is going to try that on Wednesday.
I should start a whole other thread, because I've also noticed that when I ride occasionally I feel this horrible grinding sensation through the pedals. But apparently the bottom bracket is fine. I don't get it. It'll feel like I'm riding over asphalt that is in poor shape, but I'll only feel it through my pedals, and only when I'm pedalling which is why I thought it was the bottom bracket. But then when the alignment issue came up I wondered if perhaps it's all related. I don't know. I'm getting a bit frustrated.
