Al. I think they are billit hubs, whatever that means, I will check tomorrow. The texture looks rough, but that could be due to it going around the track a few times after the break. It does not look like a clean break. I found it because I was prepping for willow springs and found what I thought was a loose bearing that needed adjustment. The cross section is roughly 5/16's at the break. The shaft is inside the hub. The hub has 2 bearings on the outside of the hub, both press fit on the hub. The outside of the bearings then ride inside their races. The races are located in the uprights. Scott
