To be honest, there is just SO much on this forum, it's a bit overwhelming.
So I'm making a thread about my specific question.

I'm new to riding fixed, and currently riding a 48/16 setup with 170mm crank.
I'm thinking of getting a 160mm crank with 46 teeth.

I live in central IL, and have slight hills, but nothing too drastic.
Was wondering how much of a difference I will notice.

Thanks for the help.
