I have nearly 2,400 miles on a set of Vittoria Randonneurs 700x32 that came stock on an Orbea Carpe.
The rear is wearing very thin, looking for replacements. Fairly happy with the Vittorias. They have worn pretty well and only flatted once.
1. Must have reflective sidewall.
2. Good flat protection.
My commute is 100% pavement, some of that on a very wide shoulder littered with a lot of debris, pebbles, misc "FOD" junk. I do like to get out on a converted railroad bed "greenway" trail occasionally and there are miles of fine gravel. I use this bike for commuting and "sport" riding, I will ride at least one century this year on it.
Ideas? Suggestions? Will consider dropping to 700x28's to perk up performance, but at what cost to flat protection?
