I noticed with the bike I've been commuting on that the cold affects how it shifts. It wasn't shifting perfectly... there was always some gears that would try to shift on their own when I used them. I think it was because of a bent derailer hanger. But on cold mornings it would shift perfectly!
I recently bought another bike that I am getting tweaked how I want it. It shifts great. But this morning (cold) it was trying to shift out of the gear it was in.
Is this because the cables expand/contract with the temperature change? Is there a way to compensate for this?
I live in south Texas, so it doesn't get really cold but it also doesn't stay cold. So I can't have a winter and summer setup. The temperature tomorrow might be back to blazing hot...
Thanks for advice!
