As you can see the NR does not really care to be stretched to such limits.
I'm planning to try a 6 speed Ultra freewheel, set up as 14-16-19-23-26-34 using a Eco DuoPar RD. At the same time I could change the crankset. I have new or nearly new 51, 50, 49, 48, 47, 46, 44 & 42 tooth chainrings. Also the free wheel is a Suntour perfect and I have a great supply of cogs so can build it with any gear combination from 13 to I believe a 38 or 40.
I'd love suggestions!
Bob,
If you post or PM me your freewheel tooth counts, I can do the math; I have an Excel spreadsheet set up for it. I can also design a HS gearing for you if you want to try an optimized one, since you have a supply of chainrings and cogs. I'd like to try it, but I don't have much in spare parts. Local flippers have all the decent used bikes, and they get out at 8 am to get'em.
Same offer to the Forum!
