Dirt or asphalt, mountain or urban, geared or singlespeed, the moniker has never rang more true than on the updated 2017 Santa Cruz Chameleon. 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 12x148mm-spaced, and singlespeed are 12x142mm. The components of the bike on the picture may differ from the actual configuration, see below for component description. Details include 27.5 Plus and 29-inch wheel compatibility, interchangeable dropouts for gears or single speed, stealth dropper seatpost routing, threaded bottom bracket, and two bottle cage mounts. Fork compatibility: 120-140mm. Max tire size: 3.0" for 27.5", 2.5" for 29".
