Should I complain at the LBS about a new dead-on true wheel with unequal spoke tension?

As mentioned by @JoeK, how much you spent, and what you told the shop the wheel will be used for will play a big factor in deciding if the wheel is fit for purpose. If you told them it was a to keep a ...

Can I replace just the internals of a wheel's hub instead of the whole wheel?

Yes, it is sensible. On the assumption this is an aluminium rim. Wheels don’t just wear from rim braking. If this is a wheel used for off-road there will be accumulated fatigue in the rim at the spoke ...

Momentum and gyroscopic difference between wheel sizes
