Had to be me last Sunday. Off for a ride, got everything, off I go. At about 45 miles and 6 miles from home I have a flat. No problem, 2 x tubes, levers in seat pack.........which isn't attached to the saddle so my seat pack was/is out there somewhere. I failed to engage the clip thing!!!! My wife doesn't drive so I set off walking. 4 miles later, got to my lbs which was open. They kindly GAVE me a tube, loaned the levers and I was home 15 mins later. Heel pads and 1 cleat ruined.
