It's been zero maintenance so I guess pretty well. I cleaned and lubed the chain last week, then took the wheel off and flipped it, just to make sure that was all still doable and it was. I haven't heard a peep out of the chain rattling against anything. So it's a keeper as far as I'm concerned.

It's enclosed now btw, black Coroplast sides. I had to use straps over the outside of the guard to hold the sides on.
