I have a pair of 60's TA track cranks and I broke one of the 5 nut/sheath that the bolt srews into. I tightened too much. You know one of the five little bolts that tightens the chainring to the crank...
Anyone have one of those nut/bolts for those cranks lying around? If you don't know what i'm talking about, but think you might have one, I can email you a picute of the part and place on the cranks it threads in.
Thanks,
