Today I put a new front tire and tube on my Roam-2 as it was flat when I went out to the garage to go for a ride. Fortunately, it went flat while sitting in the garage and not while I was out riding it.
Put on a new 700x32 Vittoria Zaffiro that cost all of $10 U.S. at Chain Reaction on closeout. Can't beat that with a stick. I also replaced the tube, but had to use one that was intended for a narrower 18-26mm tire as I didn't have any extra larger tubes lying around. Guess it's time to replenish my stock.
Anyway, I'm back in action.
