Your basic instinct is right. If it ain't broke, don't fix it.
Yes, wheels do "settle in". This will happen if you have someone screw around with your wheels now, and then when you get a few miles down the road everything could go pear shaped.
It is better to hit the road with the wheels you have now in a known and stable condition.
I am very impressed how well you have done everything exactly right in your preparations. Have a great journey!
Hey thanks! Another sixty mile loop around the city today in six hours, that time including a half hour for lunch, pee stops, stretches of sidewalk riding where necessary, and many traffic lights. This including a stretch mid-route with steep enough hills to leave me dizzy, faint and gasping. Great stuff
In this city you climb as you head north, time permitting I have worked out a seventy-mile loop incorporating a 28 mile northbound transect of the city (including said hills) beginning at mile twenty four, the last 18 miles home after that incorporating a lot of downgrades.
Surprising thing is I can do this with a knee that is still marginal, I have to be careful to go gentle on it and spin a gear lower than I otherwise would. At least the pain when it does hurt has relocated, which I'm taking as a sign of progress. On the one hand its frustrating on account of without the knee problem I would be able to just crank hard and work on fitness. On the other hand I'm grateful that I can even ride this far, I got friends and family my age (56) who cant.
I don't see that this is as an outrageous expectation when buying a decent set of wheels. Even cheaper machine-made wheels can be tremendously improved when the above is done and I take care of this myself rather than taking them to a pro wheel-builder.
