Thanks. I'm thinking biggish tires for the added float over potholes and such. When the road is clear I have no problem avoiding debris and holes, but when all that stuff is hidden by a little snow or slush...

My everyday tires are 27 x 1 1/4 serfas secas. I'm not really tempted to ever go skinnier than that for anything.

Never thought about that benefit of deep V rims. interesting. I'm not buying wheels right now, though. Starting cheap and I'll add on as I go if I like riding it fixie. I guess another option I'm sort of considering is a 3-speed coaster hub, but well... I don't know. I'll try fixed first. At this point all I need is tires, a cog, a lockring, and some loctite. It might as well be free.
