large bore bearings are used to reduce rolling resistance

For my curiosity, can you explain the reason behind this? Is it something to do with a larger shaft/bore surface area to spread the load over, or more rolling elements in the bearing, or something else?

Thanks,

I imagine it has a lot to do with maintenance as well. The wheel, shaft, and spacers are all one part now. Not to mention, it looks incredible.

This is so cool.

42mm OD/30mm ID large bore bearings are used to reduce rolling resistance

Do you have an estimate of how much?

I'm curious why you decided to make the end of the shaft bore a hemisphere as opposed to a flat-ish end.

How does having the wheel like this improve maintenance over the current WCD set up?
