I went to grab my folder this afternoon for my daily commute and discovered that
my front tire (20 x 135 Marathon Plus) was flat. First puncture in hundreds of miles of riding over glass-strewn streets. Not sure what caused it, but there was a clean cut in the tube about 1/8" long. Did the commute on my mountain bike, which sports Marathon Plus Tours. Only one flat on those after several long tours and lots of riding around town and along country trails.
