I just received mine, bought the 45mm with steel bearings. I noticed the rear wheel doesn't spin as smoothly and freely I thought it should, there are some resistance when I spin the axle, and comparing to another wheel I have it's free wheeling noticeably shorter. I've asked EliteWheels about this and below is their reply:

"We have received feedback from engineers. Through the video, we think bearing is no problem. You only need to install the wheel to the frame. The wheel can work normally because of the contact area between the bearing and the axle we use for this wheel. It is relatively large, so there will be some resistance, but it can better improve the waterproof performance of the hub, and it smooth when riding."

Not sure if this is normal and if anyone else's wheel is the same? I've attached the video and hope that's clear to see.
