I used them once, alloy body with sealed bearing. Didn't work that great. It sure as hell wasn't better. At least in the case of shimano, they have it pretty well figured out, it seems to me, one wheel has a ceramic bearing the other has a steel bushing. One of them needs to float back and forth a small amount. I've never had any issues.....,.
