I have an '06 specialized langster with the stock 700x23 mondo tires. I got off of it to day and noticed a 1cm+ long split/cut on the tire. There is still plenty of pressure but I will have to replace it. So my question is what should be done? I have had the Specilized Armadillos recommended to me but I don't like the color of them (dumb I know but the bike is black and the tires are brown). I use the bike for city commuting in Portland OR. Any help?
