SEND-IT-ALL ON THE ALL NEW SENTINEL
A bike that says yes to every trail, every ride and begs for more.
The Sentinel rides the lines between planted bottomless sender and playful, poppy trail pony. This leaves it right in the sweet spot, as we like to call it. It's versatile attitude helps riders excel and push their limits, making it the one bike most will need. Its intuitive nature is easy to get acquainted with; you'll find yourself sending lines, jumps, and maneuvers you always felt were beyond your ability. Where before you went around, now you go over. Where you pushed up, now you pedal. Where you rolled, now you boost. It's time to Send-It-All.
