It's looking pretty good. When do you think you will be having more of it done?

Bearings are in the wheel and sprockets are mounted directly to the wheel. The shaft doesn't spin. Dead and live axels have their advantages. If you do dead axels right, you can just remove to bolts holding it in place and the shaft can just move out of the way, making wheel replacement very easy.

What 1519 has done in the past is cut vacuum tube and zip-tie it to the corner wheels. They still get a bit of forward traction, but it greatly reduces the side scrub.
