The other retirement

The valve nut for my front inner tube bent and then broke off this afternoon as I was preparing for another go at my own private time trial. This situation necessitated replacing, after two-and-a-half years and how many thousands of miles I don't know, the original tube. After putting on the new tube and several attempts at refitting the original front tire, it became clear that the bead of the tire would not seat properly. The tire, like the tube, served me extraordinarily well. Both will be missed.

Retired

A friend of mine recently had his first experience getting a flat fixed. That made me realize that I'd ho-hummed getting on my third tire and fourth or fifth tube on my rear wheel over the weekend. The first tube I replaced took about an hour; the procedure for time and tubes this time took about 10 minutes (the first tube I put on had two holes in it). I've read rears go bad more quickly because they bear more weight. A bead failed on the first tire. The second tire died a death of maybe a dozen cuts and nicks. It also appeared to be fatally compromised by what felt like several strands of jewelry wire. The third tire is holding up well after 16 miles. Those first two tires managed to survive a variety of indignities, including rocks, nails and cotter pins. The tubes did not endure the indignities as well and suffered from some I inflicted, such as a valve stem I kicked off and particularly pointy rock that I hit at just the wrong angle. Not to mention nails, pins and wire. Yet at the other end of the bike, after thousands (eight? 10?) the original front tire thrives. Go figure.
