16t, 17t, or 18t cog?
Just got my Windsor Clockwork, and I'm going to head over to my LBS to pick up a fixed cog for it. I'd like some input on what size I should get for what I intend to do with the bike.
I'm going to be riding around campus in a moderately flat area with a lot of pedestrian and car traffic. Right now I'm riding 46/16 with a freewheel, but I'm not sure if that gear ratio will be too high to stop quickly when pedestrians decide to run in front of me or when cars decide they want to merge without looking if I'm riding fixed. I was thinking about going up to a 17t or 18t cog.
I don't have the money to get more than one cog, do any of you who ride in cities/college campuses have any input?
