Best all-around gearing?
I'm kinda new to the single speed/fixed gear genre, but I hear it's the in thing right now. Hoping to renovate some older bikes I've got lying around to sell - not having to attach deraillers and run cables sounds great. Most of them have a standard crank up front - like 52. What would be a good gear to run in back for all around riding - some hills, mostly level in town riding?
