How often do you adjust the back wheel/chain?
I find myself adjusting the back wheel about every 3-4 days (i.e. 50-70 miles, rolling hills). Within those 3-4 days, my chain goes from 1/2 inch play to 1 inch of play.
Is this normal? I have tried tightening as much as the wrench and my arms allow. What's going on here?
