When I mounted the Bionx wheel on my bike I noticed that the gears of the freewheel noticeably waffled as the wheel was spun - approx. 1 mm at the largest gear. The dealer and I verified that it was a manufacturing default in the way the threads were cut into the hub - not a freewheel problem. The dealer was reluctant to return the wheel to the manufacturer. He said there was often waffling in freewheel setups. I contacted a friend who knows a lot more about bikes than I do who thought it wouldn't be a problem unless the gears made a lot of noise in operation. I'm accepting the dealer's assessment and completing the installation. But I consider it gross incompetence on the part of a manufacturer who enjoys a very good reputation on the web. It means the machine that cut the threads into the hub was misaligned during the cutting. Not good!

sandorszabo,
I have worked on bikes for several decades and I can tell you that what you describe may still function but it will cause excessive noise along with excessive and uneven ware. If it were me I would not accept the wheel. There is no good reason to accept faulty equipment just because someone is too lazy to do their job and get you a corrected part. I have had trouble getting things like this fixed myself and I have come up with a way to get what I want. I buy one more of the same product and when it arrives I swap the good and bad parts then return the bad parts for a refund. Sometimes you have to pay a restocking fee but that is better than putting up with substandard parts.
FWIW my opinion,

I've found my hub wheel does the same thing. Only very slightly, but that was not the case when I tested the bike with its original wheel. I thought, "This can't be good" - The wheel seems like it will vibrate out of the dropouts, AND my gears crackle and pop. Any way (for a lack of funds) I can remove the innards of the wheel and tighten up those gears myself? Or has anyone found this to be strictly a manufacturers defect?
