Easy to do and it moves it a mm or so inboard which now leaves a bigger gap between the rings than normal.

When downshifting from the big to small ring, the chain sometimes slips between the rings and spins freely. This happen more often when in the smaller cogs. I have to switch to the middle cogs and shift up and down again to get the chain on the small ring. Is there anything I can adjust to remedy this issue?<br /></p>
