Thanks for your reply. The first two paragraphs are over my head. I just ride bikes and am not fond of even blowing up tyres!

The info I could understand is useful. During the trip I put my front wheel on my wife's bike and hers on mine. We both have Surly LHTs. Hers has the stock wheels. Instantly as she rode the clanging started and she is much lighter than me. My bike with her wheel was silent.
