"I think you need reading glasses Doug!" What he thought was 110 was actually closer to 140.
Oh man.
I had a pump like that and was all I used in my earlier years. My Trek 460 had Vredestein Ricorso 23's with a folding bead, excellent training tires. While on a longer ride I hear a strange WUB WUB WUB coming from down near the front brake. The bead had lifted and a freaky black bulge getting bigger and bigger, dragging by the brake caliper. Of course, as soon as I hit the brake there was a pop and hiss.
That was when I backed pressure down 10psi. This has been the only flat on the front for me, ever.
