Quick, when in SoCal (note pertinence), what is the inside diameter of a cogset spacer, ie the kind used to space a cog on a singlespeed conversion? What's the OD?
Erik, have you posted this on the Singlespeed forum? Also try the 29er forum.
It's cool -- I got home and got it done. I used to know this... Anyway, we're making "medals" for Cub Scouts out of old cogs and now I know the diameter for the stickers going in the middle.
Next, I'm going to crochet some gloves.
