Well, I got and disassembled a total of 4 Suntour freewheels and tried putting together what I ideally wanted. I couldn't make a 13T sprocket work with what else I had so I put this together and installed it on the bike tonight:
The only twitchy shift is around the 20-23 sprockets. Otherwise I think it works pretty good. Drop the useless top three in the 28 ring and I have a pretty even 15 gears from 22 to 96 gear inches. I would have liked to get over 100 gear inches on the top end but I'll have to live without unless I come up with some odd sprockets.
Here's the stock gearing for comparison:
I think it's much better now:
1) More even shifts (except for that one).
2) Almost no duplication.
3) Got lower gearing without sacrificing the stock top end.
4) With the 28-34 combo I'll be able to spin up danged near anything.
I rode it just briefly tonight and it was obvious out of the gate that it was different. Once I get used to shifting the barcons I'm sure I'll get more in tune with the half step and hopefully it will work well for me.
