Today, I experienced a blow-out (on the 5200). Fortunately, it was the rear tire and I was only riding about 15 mph. After the pop, I rode a short distance before I knew it was me who flatted. I was riding with two male church members. The ladies (3) rode together. So, I ended up with an abbreviated ride. My CO2 device (a new non-tested one) did not work. Further, I failed to have a lever in my kit–my bad! Using keys to break the bead, I broke one of my mate’s key. What a ride. Luckily, we were not too far from our start point, so the 2 guys returned to get a vehicle to come pick me up–another first. Anyway here is the ride, as short as it was.
