REFINING THE LEGEND
The new Sentinel may have a similar silhouette, but we've fully redesigned the frame with updated industrial design, features, and geometry to turn it up a notch. The leverage curve supports the bike higher in its travel, leaving plenty of room for big hits, while keeping it light on its feet to remain nimble and quick everywhere else. This gives it the lively, sporty attitude felt in the Spur and Smuggler without sacrificing its capabilities in rougher terrain. New size specific chainstays and a 64 degree headtube angle keep riders balanced with great traction on climbs and descents. All of this creates a bike that encourages new riders to push their limits, while ensuring a seasoned pro feels none.
REFINED DETAILS
We took a step back and looked for ways to improve the Sentinel, not just for the sake of change but for real, tangible steps forward that riders will feel and experience.
We added internal frame storage in the downtube of our carbon frame. The B.O.O.M. Box (Burritos Or Other Munchies) is positioned below and isolated from the water-bottle cage mount. This allows you to leave your bottle installed in your cage while easily getting into the B.O.O.M. Box, reducing clutter and fuss on the trail. It also prevents noise by not placing any weight on the door itself. With an easy access lever and two supplied gear bags, riders can stow away snacks, tools, a tube, or anything else they want to have along for the ride
GEO-ADJUST FLIP CHIP
The lower shock mount has a geo-adjust flip chip to accommodate mixed wheels, and features a new design that allows water, dirt and debris to easily wash away. Low for 29" rear wheel, high for 27.5".
MUD GUARD
The Sentinel comes with a pre-installed mud guard to protect the main pivot area, improving the bearing life.
CHAINSTAY PROTECTOR
An all-new chainstay protector minimizes chain slap, so you can enjoy the sound of your favorite turns. The "pillow top" design features large rubber pillows that dampen sound and protect the chainstay.
CABLE PORTS
Cable ports on the side of the headtube allow for easy and simple cable routing with customizable options for mechanical or wireless shifting as well as left or right rear brake setups. The new port stops cables from getting kinked during a crash and holds them tight to prevent rattling. If you aren't using the port at all, simply cover it with the supplied insert to prevent dirt or water from getting inside your frame and keep a clean aesthetic. These ports help improve the looks of the frame while remaining functional and simple for maintenance.
