I roll on a Mercier Fixie that I bought as a winter bike for VT
but ended up liking it so much that I dont want to beat it up
as a winter bike. For 347.00 it cant be beaten ! That being said,
I have to ride the 700x23's very gingerly......My geared bikes
are 27x1.2's which I find to be a perfect tire for around here.
Not to much rolling resistance and can take a farm road beating.
As much as I like the fixie, realisticly I think 27's are the way to go.
