I got my LBS to build my rear wheel/cog/crankset up on my fixed gear. I'm running a 48x16 right now, and want to change the cog to a 18 for various reasons, but I don't remember what diameter chain I'm running... I can't remember if it's 3/32 or 1/8". Is there any way to check?
edit: 3/32, not 1/4"
