Another commuting flat yesterday. I rode the Grandis which wears 23mm Veloflex Masters. A few miles into the ride home the rear went flat. On an uphill. Fortunately there was a comfy stone and concrete wall to sit on and grass to lay down the bike. I found a medium-size puncture, patched it up. A local resident going out to his car even asked if I had everything I needed. Yes, thank you. I pumped it up, mounted the tire, rode home. Uneventful except for the minor delay.
