So I am trying to remedy an issue I keep having with gearing on my skip-tooth bikes. There just seems to be such a tall gearing when I use the standard mens 26 tooth front chain ring and the rear 9 tooth cogs that are available to retro fit on the newer shimano hubs. I guess what I am asking is what other rear cogs with more teeth are out there. I need to get my hands on one so I can make a program of it so I can make some retro fit cogs with a shorter gear. Does anyone have some other options for skip-tooth cogs I could borrow or buy?
