I've had my PL-350 kit for a few months now. While the electrical components are working flawlessly, I've noticed a mechanical defect. The cassette is not properly aligned with the axle. The cassette wobbles about when the wheel is in motion. I know that some wobble is not uncommon and is usually not problematic. However in this case, the wobble seems excessive. Even after adjusting the gears, they never seem to align well enough. There is always gear chatter.
I have complained to my bike dealer about this problem. They tried replacing the cassette and tuning the gears, but the problem is still there. They've also told me that cassettes often wobble on their axles, but I haven't been able to find another bike that has nearly as much wobble. I suppose I should have a conversation with the bionx folks about this and see if there's a remedy. Has anybody else experienced excessive cassette wobble on their bionx wheel?
