Re: Thing to do / know before getting a Jack Shaft
My experience had been very troubled. After fixing "touching chain" issues with 3 spacer washers on the chainring posts and a washer on the Jack Shaft . 3 miles later the freewheel blows apart causing the chain to warp the small chainring, ruin the Jump Stop and the chain itself. The tool I ordered to remove the destroyed freewheel did not work and so I had to get new crank arms. 10 days and $140.00 later I am hoping to rebuild with extra plastic chain guards sandwiched on both sides of chain rings to prevent deraillments. Anybody else having these problems?
