A lot of talk here about tire width, but what about height?
On my bike-Lynskey R230 rim brake, there is plenty of clearance laterally, but minimal between the top of the tire and underside of the fork. I have had to stop a few times to clear leave, pebbles, etc. Conti 23's are the biggest that fit.
I am looking for new (carbon) wheels and am hoping that wider rims will reduce the "lightbulb effect" and allow me to run bigger tires.
I am hoping to get 59.5 miles of comfort and am willing to concede the 2 city limits sign sprints.
