The Big Rock is here to set the record straight - A stiff frame and long wheelbase create an adventure-proven platform ready to put a smile on your face on your next ride.
Road, gravel, dirt, it can do it all with speed and confidence. The Big Rock is designed and tested on the fire roads, back roads and secret dirt routes of Marin County, California.

With thru-axles front and rear, the Big Rock keeps its composure over the rough stuff while the integrated disc brake mounts give you the ultimate stopping ability.

Rear rack mounts let you load up for the day or weekend of adventure.
