Hi, I tried a few search's and found some needed info, but still have some questions. The stock gearing is 32/20. I am going to mount Bontrager 700x35 Select K's. Will be used for communting. Mostly flat depending on route. One way is 1.6 mi plus whatever I add on going home. I think the crank is 104 spacing. The chain ring is currently on the inside of the crank and close to the chain stay. With a bigger chain ring, it will mount to the outside of the crank. How do I space the rear cog out to keep the chain in line? What type of cog and where do I get them?
Thanks for the help, MikeB
