Has any one had trouble with their rear wheels yet? I did because I
cary too much weight and go around corners fast.

But after having my trike wheels custom built the spokes started
working loose every few weeks because the shop copied the light duty
wheel's offset dish pattern that came with the trike. A much steeper
angle on the disc brake side, like a bike's front disc brake wheel.

There is a theory that says that the spokes on the disc brake side of
a bike wheel needs to be shorter because the brakes will pull the
spokes on that side first, yet hubs do not twist. The only reason
that the spokes need to be shorter on that side is to make it fit in
the wheel well.

Some people think that front wheel spoke tension should be less than
the rear because they think the high tension will collapse the wheel.
Yet the rear wheel of a bike is always asymmetrical making it much
less stable when it is subjected to high torque..... One side is
inherently tighter, so of course it will collapse.

JOBST BRANDT (The Bicycle Wheel): The only reason that any bike wheel
is built lopsided is to make it easyer to build a frame that will
hold both wheels in alignment with each other. In effect a lop sided
wheel (asymmetricaly dished) is only half as strong as one with all
the spokes the same length. (pages 32 & 39)
