Back in the mid-70's, when dinos ruled the earth. the current fad of the time was drilling out parts
and cutting anthing off that seemed superfluous(sp?). This included the filing off of every other
chainring tooth. It gave a little extra room for the chain to catch on the rings. All of a sudden,
even poor shifting front deraillers worked better. Some times a lot better. I myself have
filed/ground off each tooth above the spider arms on a Rans Rocket. 5 teeth max. It really helps the
chain to engage quicker And if you are having the same type of problem on the big cog in the back,
the same thing helps. Paul Milner
