A Suntour Ultra-Six always seemed like the best choice if one wished to use the P.C. In effect, that is what you have. Still, even if six cogs is enough (are enough?) I'd rather have mine spaced "regular" for easier shifting with the NR/SR rear. I never was very good at friction shifting on narrow-spaced freewheels. 12 tooth.... indeed, what would I do with a 12? Make up lost ground on the downhills, I guess.

So now it's a six-speed, with the little trigger to drop the chain to where the 7th cog would origanally have been. After all, who could possible need a 12t at my age?
