This is for a singlespeed.
I'm thinking I could save some weight by running a low teeth combo of chainring & cog like a 34 x 12 which equals 74.5 gear inches.
Anyone do this? How much weight savings? Would it be worth it for a closet weight weenie?
I figure the chain would be shorter and the smaller chainring and cog would help shave off some weight.
I know less teeth would mean faster wear, but I am not worried too much about that since chains are relatively cheap.
