47 mile B class “Start the Season” Ride

Sat, April 13, 2019 11:00 AM | Thomas Short

Leader:  Tom Short

Members:  Linda Bankerd and Fred Sawyer

Weather:  Ride start was postponed from 9:00 to 11:00 due to early a.m. rain. Postponement for 2 hours was a great decision as we had perfect riding temperature (in short sleeves) and a clear blue sky. 

Mechanicals:  Linda was losing air from her back tire and was down to about 20 psi when we stopped to look at it. Our first thought that it was a slow leak and if we just added air we could ride the remaining 6 or 7 miles back. Linda added air and when she removed the pump the tube’s valve stem blew out. Just then a car stopped to offer assistance and Linda decided to load her bike in his car and ride with him. I then continued the ride. 

Ride Report:  Beautiful day, good roads, nice route, and courteous drivers.  As reported above, Linda had a flat but did not lose very much mileage as it was relatively close to ride end. I had never ridden with Fred Sawyer before and he was a very good riding companion. He was riding a new bike that was designed for gravel, rough roads, and smooth dirt trails. He was very happy with his bike. 

Lesson I hope to learn:  Fred is a strong rider and was ahead of Linda and me.  I tried to telephone him to let him know that we were delayed but I could not decipher his phone number. The lesson is if you are the ride leader make sure you can read what others wrote.

    You've really got to watch those tubes with removable valve cores. Some pumps, particularly those with thread-on hoses, will unscrew them when you remove the pump. Lezyne even recommends using blue Locktite on removable valve cores to prevent their hose connection unscrewing the valve cores. How that's supposed to work with a tubeless setup remains a mystery, though...

      I think that more tube are coming with removable cores now. It could be because of more wheels needing valve extenders. I have found some tubes with untightened removable cores (from the factory). I try to inspect them before installing or placing them in a bike bag. I have never had a valve core that I tightened come loose using a screw on tire pump hose. Fortunately if the core unscrews with the thread on hose, you usually won't lose them. But if you don't have a small valve core wrench, the tube is useless with a screw on pump. A metal valve cap might work for tightening - I'll need to check. As to tubeless tire valves, the valve core is removed to put sealant in. I have also had to remove the valve core to clean the sealant out of it.
