I'm building a bicycle wheel today*. I have to build one because the speciifc wheel i need is bizarre and impossible to buy or find. This is because I am refurbing Lydia's ancient Schwinn adult tricycle. The wheel is 24in, internal three speed. i tried to open and fix the hub. That was poor judgment. It is better to build a wheel around a working hub than to fix one of those insane mechanisms. Sheldon Brown is heroic. Lacing went way better than it should have. Still plenty of truing to do.
*Bicycle mechanics say 'build' where most people mean 'assemble'. I'll gladly carry the convention forward –– makes me sound cooler.
