I noticed that I have trouble shifting the rear derailleur the next day after the rain. I tried to mess with the adjustments, now it's slightly better but not perfect like before. I know that I need to loosen the cable to aid shifting to a smaller sprocket and tighten for larger sprocket, but now I have trouble shifting to larger sprocket (gotta "overshift" by pressing the lever further than the click), but when I tighten the cable till this is ok, the shifting to the smaller sprocket becomes really difficult. What should I do? Do you think the rain got in the rear derailleur and messed it all up?
Thanks,
Zed
