Wheel Balance ?
Do Flow rims sometimes have uneven weight balance ? Thanx
Nope. No bicycle wheel does.
When I have my bike in a stand or upside down and give the cranks a good spin the rear wheel makes the bike shimmy like an unbalanced wheel, even without a tire mounted. The hub also has an uneven oscillating sound instead of a steady buzz. I don't feel it while I'm riding, but I hear it. The wheel is true laterally and radially. What would cause it to shimmy and have the uneven hub sound. Thanx.
Not true. Few, if any, bicycle wheels are perfectly balanced, but it does not really matter when riding.

I would consider a rim thats out of balance to be in need of balancing. Bike wheels arent in need of balancing, so I wouldnt say they're "out" of balance. Maybe semantics, but out-of-balance sounds like a problem to me, so I wouldnt say it applies.
Theres going to be a little weight variance, but they are balanced. Depending on your hub, you can have a pretty good variance in the tone coming from the engagement mechanism. Kings are pretty famous for that when new.
I have never seen a balanced bicycle wheel assembly. All of mine shake or shimmy in the stand if spinning the wheel up fast. With that said, no one except maybe people competing for land speed records balances bicycle wheels.
Yes rims are not balanced from the factory, none of em, the weld or pinning of the joint adds weight opposite of the valve hole, being that everyone wants to save weight and the only way to balance a rim without reducing it's strength is to add weight where needed, it isn't done.
Lastly even when hitting 55 mph down a really steep paved road I felt no instability with my out of balance wheels. So it isn't a problem and it isn't anything you will ever notice on the trail.
As for the varying pitch on the king hub, I have a 14 year old king hub that does that and it operates perfectly so don't worry about it.
Hey guys thanx a million. Much appreciated.
