There are truing stands on the market now that have dial
gauges that will show you to the tenth of a millimeter how round and true your
wheels are. They present a beautiful picture of precision that the bare steel
pointers of my Park TS-2 seems to lack.
People who use them talk about how accurate they are, how
quickly they can get a wheel true and round.
Thanks, but no thanks. When I get the wheel round enough
that the pointer is a millimeter off the rim in both lateral and radial
measure, and when my dishing tool says the wheel is centered on the axle, I say
that deviation is small enough, and work only with the tension meter. I will
give up a deviation that will be undetectable while you ride the bike to have
the tension closer to even. Remember, we are riding on pavement, not a
brand-new velodrome with a polished concrete surface.
If I had a better grasp of the mathematics and physics
involved, I could manipulate the formulae and finite element analysis presented
in Jobst Brandt’s “The Bicycle Wheel” to prove this thesis mathematically, but
I don’t ride numbers. I ride bicycles. I have heard from customers and felt on
my own bikes that my wheels just ride better. I believe it is because I concentrate
most on even spoke tension.
