Works great.
On the advice of others here, I chose and purchased a NOS Suntour Power Shifter assembly off Ebay. It also works great, much better than the Shimano assemblies of the day. Good luck, have fun.
Very nice! I unfortunately chucked my old cable guides when I did my bike into a fixed conversion. I know, dumb. I'm reconverting her into a normal road bike after moving down to Maryland (holy crap, hills!), so I was wondering if there was any new stock of that particular item?
And yes, I am definitely converting to downtube shifters, as I plan to use her for some club rides.
