the miracle of reinflation?
Friday I went riding and got 9 miles into a 15 mile ride and got a rear flat. Could not find anything obvious. Pumped up the tube twice and it deflated both times. When I got home I used my larger pump and filled it to 120psi. Next morning it was still at 120. Went riding 22 miles, fully expecting to replace the tube during the ride. It never deflated - nor did it on Sunday's 23 mile ride. the valve was hand tightened, no cap, so how does this happen?
