Anybody use the nylon rear sprockets claimed to run quieter and absorb some lubrication? Pictured first is the early white ones and later  [/a]black upgrades. Popular 1975, 1976  |

My restored bike had a white one on it when I found it. It had a couple more teeth than stock to try and get around the RE growl at the then 55 MPH speed limit. It was so worn out that the chain had been jumping over the worn off teeth and damaged the chain guard. I am sure it was installed around 1976 as you mentioned and the bike only had 7,000 mile when I found it, so that sprocket didn't last very long.

Interesting that at least one other person tried the nylon sprockets. The original chains
were short lived even with good lubrication. I saw at least one customers bike sprocket
GT-750, also with damaged (lost) teeth. I am sure a worn chain is a precursor to sprocket
failure. One thing I am not sure of is if the nylon sprocket amplifies any inherent low
frequency vibration. Tim

I remember the nylon sprockets down here but never tried them. My memory is they weren't marketed for road bikes for very long.
