The Sentinel inspires confidence like you're wearing full body armor. It's forgiving do-it-all attitude truly blurs the lines between planted bottomless sender and playful poppy trail pony. Whether you're chasing EWS dreams or just a weekend afternoon escape, it will bring out the best in you.
So 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.

Frame Material
The Sentinel carbon uses premium Japanese Toray fiber using a unique latex coated EPS molding process to create tighter edge radius control using less material. The Sentinel alloy features a frame made from tough and dependable heat treated 6061 aluminum to strike the right balance of strength, durability and ride quality.
Pivot Technology
Collet main pivot technology improves rear end stiffness and keeps your pivot hardware tight. Additional bearing shields prevent main pivot bearing contamination when washing your bike or riding in wet conditions.
Frame Protection
We keep your bike rides quiet and your frame safe from damage with fully integrated, flush-mounted rubber frame protection at all critical areas. In addition to downtube and seatstay protection, the ribbed chainstay protector features expanded coverage of the rear dropout pivot area.
Enduro Max Bearings
We exclusively use Enduro Max suspension pivot specific bearings in standard sizes that are readily available worldwide. Dual bearings are used at the dropout pivots for frame stiffness and additional c-clips lock the rocker bearings in place under torsional loads.
Gear Accessory Mount
Our underside top-tube accessory mount allows you to carry a spare tube or other goodies safely on your frame in case you are looking to ditch the backpack.
Mega Seatpost Insertion
Dropper posts keep getting longer so we combine short seat tube lengths with mega seatpost insertion to help get your saddle completely out of the way.
Tire Clearance
Ample clearance for mud and tires up to 2.6' width.
User Friendly Cable Routing
To simplify maintenance and keep your bike noise free, the rear derailleur cable is routed through guide tubes in the front triangle and chainstay. Feature available on carbon framesets only.
Threaded BB
A standard 73mm threaded bottom bracket shell makes crankset maintenance hassle-free and prevents unwanted press-fit BB related noises.
Press In Headset
Our ZS44/ZS56 press in headset gives you the freedom to use angle adjust headsets if you feel the need to make your bike a touch slacker or a touch steeper. Angleset headset does not come with framesets or complete bikes.
Water Bottle Compatibility
We keep your water bottle clean inside the front triangle so you can keep hydrated without worrying about mud making it to your mouth.
