Re: Shifter Bike Freewheel Skipping?
A couple years ago....I had a freewheel slip on one of my regular (non-motorized) bikes.
It was doing exactly the same thing....I would be pedaling and it would slip and the pedals would advance about 45 degrees (out of a full 360 degree pedal stroke)
The problem turned out to be old congealed grease in the freehub body as it was catching and not releasing the internal sprags from time to time.
If some's good...more is better and too much ain't enough.
