Surly Karate Monkey Rigid

Surly Karate Monkey Rigid

This bike is a rigid mountain bike go-anywhere, trail capable monster! My buddy rode the Baja Divide on this bike - it's more than capable as a bikepacking / adventure touring bike, but it is also suspension fork compatible and can shred singletrack suspension or rigid. This is an excellent 12-speed Shimano build with reliable Avid cable brakes!
