I picked up a Velo Orange split race headset for a project and very much like the concept. As a DIY bike mechanic, the split race means that I can do clean headset replacements without procuring expensive tools or resorting to DIY hacks for the purpose. And, for headsets like the Velo Orange one that are running cartridge bearings rather than loose ball bearings, the cartridge assembly itself just bridges the gap. Unless I discover a good reason to not use split race headsets, I'll likely use them on as many of my bikes as I can in the future. In addition to the easy install, removal should also be easy. And for new forks, the crown race installation won't rough up the fork crown at all. I like the notion that I could pop headsets on and off of a bike without much fuss or having to sweat tolerances.
