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.
