Just realized that the title should say affecting, not effecting.... anyways..
ive recently began an overhaul on my commuter bike, and have since been commuting on my mountain bike.
On my MTB I have some Deore trigger shifters that seem to not want to grab gears in the cold. They shift great on the stand in my living room, but the other night, on my commute home it was just about 38*F and I had trouble getting the shifters to grab gears. Also the return of the thumb lever was a bit slow. Im sure this is caused by the grease in the shifter getting thicker as the weather gets colder, but im not really sure how to remedy the situation. Can I disassemble the shifter and pack it with lighter grease? some oil maybe? Ive never dismantled a trigger shifter before, so I am a little unsure about what needs to be done. If I have to live with the sloppy shifting, I guess I could, but I would really rather not.
Any help from the bike gods?
