Singlespeed bottom bracket
I recently bought a nice vintage (if mid 90s counts as such) frame
that I'm intending to turn into my first singlespeed (flip-flop) bike.
I need to buy a new (used) bottom bracket, and I don't know what the usual length for singlespeed cranks is. I also don't know much about singlespeed cranks other than what I've read from Sheldon Brown and skimming through the bike sales magazines. Any help would be appreciated (recommendations for bottom bracket length, cranks, etc.).
