I biked 88 miles yesterday, doing 2 loops of the Iron Man trail. My bike was the oldest on the course by about 20 years. She can still go like stink when I pour the coals to her.
I did an extensive search and it is nearly impossible to find a 144mm BCD sprocket less than 41 teeth.
I may swap out the rear cogs and go with a larger 54 - 55 tooth large front sprocket.
It would be great to convert to a 10 speed cassette but i think I would need to swap the rear derailer, shifter, chain and maybe the front sprockets as well. That would probably be a good $500 swap.
Looking on E-bay there is all sorts of sprocket eye candy including vintage cross drilled super light sprockets. I see how people can go nuts on old vintage bikes.
