The tiny bike parts can derail a bike ride. that almost happened before today’s bike ride. As I was about to lower my Cervelo Caledonia from the rack I squeezed the rear tire and it was flat. I repaired that tire last week and my first thought was that patch failed. Rather than switch to another bike I chose to work on the flat. I removed the tube, pumped it up and it held air. As I looked down on the floor I saw the removable Presta valve core laying there. Those removable valve cores have given me many problems. I screwed it into the valve stem and tightened with some pliers. I put the tube back in the tire and mounted it on the rim. Pumped up the tire held air while I got dressed. This delayed the start of the ride to12:27 PM. Stating later than I planned I still wanted to ride to Huffman on my Atascocita – Walden – Huffman route but left a couple of streets out. The rear tire held air for the whole ride which leads me to believe the problem was the valve core.

After finishing the ride at 2:53 PM I noticed the front derailleur wasn’t showing up on the gear page on my Bolt computer. When i tried to shift the front derailleur nothing happened. I messed with it but have not found the solution yet. I will look at later today.
