Had another flat today. Same as every other time: I've got my riding clothes on, shoes clacking on the garage floor. I air up the front tire because it's closest to me. It's fine so I move to the rear and... it's flat.
That's 4 -- all on the rear -- in the last, say, 500 miles. It's always a slow leak. MUCH easier to find the offending debris than it is the puncture in the tube. This time it was a piece of metal that looked sort of staple-like. It's also been glass and gravel in the past.
I ride this bike pretty much strictly on the road. (Occasional rail-trail, but not for weeks.) To be fair, some of the roads I ride on are in serious need of some TLC, and they've all got crap all over them. Still... I'm over it.
Suggestions? Tire liners? Brand/model of tires?
FWIW, the tires are what came with the bike, Specialized "All Condition" 700x25 with a total of about 700 miles on them.
