Spongy Road Ride on My Mountain Bike Tonight
For the first time in a long time I was able to ride my Raleigh M800 after work tonight. The temperature made it to 64 degrees and the sun was still up but fading over the horizon. The spongy part came about on the return when I noticed my front tire was losing air. I did make it home before all of the air was lost. I thought it was a puncture of some kind but when I inspected the tube I could not find one. Resorting to the water test I found the leak in the metal Presta stem where the threads begin below where the cap seats when you tighten it down. I have never had a tube fail in this manner. I usually have a spare tube but I must have used it last year so I will have to buy one tomorrow.
The statistics for the ride:
- miles = 15.05
- time = 1:12:32
- average speed = 12.4
- max speed = 19.0
- ascending = 177 ft, descending = 183
- no cadence since I do not have a sensor on this bike
