The bike stays in my garage where it is cold. The past two days I noticed my chain sagging while I coasted while I was riding to work. I also noticed that the pedals "walk" with me while I push the bike forward. At work my bike is indoors and warm and I have no issues with the chain sagging on the way home.
I decided it must be the freewheel not moving freely enough, probably because of the cold. I was thinking I should take the freewheel off and run some fresh oil into the body. My second thought was I should just toss it in the garbage and buy a new Shimano 6 speed freewheel for 20 dollars.
FWIW, the chain is 3 days old and the chain rings and derailleur are really clean. Can anyone offer up ny advice or tips?? Saving the 20 dollars would be great.
