The New Santa Cruz Chameleon

This looks like the bikepacking rig I've been looking for. 

“Dirt or asphalt, mountain or urban, geared or singlespeed—the moniker Chameleon has never rang more true than on this updated-for-2017 Santa Cruz classic. Upsized to either 29-inch or 27.5+ wheels, the Chameleon shifts from trail rally sled to bikepacker to winter slayer with simple, elegant aplomb. The wheel change is accomplished via interchangeable dropouts, and there’s a singlespeed version for each wheel size—geared dropouts are 148mm-spaced, and singlespeed are 142mm. “
