Hi Folks:
I rode a Gitane Interclub track bike all over L.A. back in the seventies,with
a front brake,and settled on 74 inches as a good gear-because of the long
gradual downhills.67 or 70 inches was neato in general,but oh so buzzy on the
descents.Climbing a little high is more tolerable.Backpedaling is the way most
people ruin their knees with a fixed.
