Always have an out. Last Thursday on my way out of the office for the holiday weekend I discovered I had a flat rear tire. A scew had punctured it somwhere on the way to work that morning, apparently. Bummer! I had replaced both tires only a few weeks before, following the big trip. Fortunately I had a plug kit and pump with me, so it only took about 45 minutes for me to plug & inflate it. This photo is the inside of the plug after I had the tire replaced. It looked pretty good & was holding air, but I've had a previous MC throw a plug out after riding on it for a while. There goes a couple hundred $$! At least John Brimberry at OTD Cycles of Oakland cut me a good price and had me in and out promptly. I like this shop!
