You guys are great! Thank you very much.
I understand what you're saying about wheels. Once my wheel got bent and I inexpertly trued it back I've been true it ever since. I do have uneven spoke tension. Again I maybe dating myself but I have dislike for rims requiring heavy duty rim tape, sharp edges and convolutions for the tube to mold to. My current Mavic Aurora has large, sharp spoke holes, a presta adapter that I keep in place with a bit of tin foil (was drilled for schraeder). The cloth rim tape works for a while then sags into the spoke holes. My fancy Mavik Kysrium Elite wheels on my Serotta are much better. I see Easyracer offers Open Pro which I also have on another bike and think of them as much lighter wheels. I weigh 185# and don't load up the bike with 50# of groceries or camping gear. Do I need a tandem wheel?
