The hard charging all-rounder is back
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 jump. Pedal up and repeat.
The Sentinel features a full carbon frame made from premium Japanese Toray fiber with a tailored blend of 24T and 30T materials to create the right balance of frame stiffness, strength, and impact toughness. Our unique latex coated EPS molding process allows for sharper frame lines and tighter edge radius control with maximum strength to weight ratio and less wasted material.
The 24% overall progression with a linear rate of change works well with air or coil shocks. The stock 62.5mm shock stroke provides 150mm of rear wheel travel, with the ability to use a 57.5mm stroke shock to get 140mm travel and large usable sag range let you custom tailor your ride.
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. All complete bikes come with longer travel dropper posts; SM 150mm, MD 180mm, LG-XXL 210mm.
