I mean, while we’re talking unicorns, I like the idea of a 5-spd **[Hammerschmidt](https://nsmb.com/articles/defense-hammerschmidt/) **that bolts of any frame with ISCG tabs, has zero drag, a perfect chainline, and is adjustable in size for different suspension geometry (can mimic different ring sizes).
I’d love to see gearboxes catch on but in my limited experience they’ve never lived up to the hype and having to invest in a proprietary frame system is a kick. It also doesn’t help that they make a perfectly beautiful human powered mountain bicycle look like a mountain moped.
