The Hard Charging All-Rounder
The Sentinel inspires confidence like you're wearing full body armour.
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 manoeuvres 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.
Speed Balanced Geometry
SBG ensures the bike maintains low speed agility, front wheel traction, and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds.
With SBG, a slacker head tube angle is combined with a all new reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes.
One of SBG's greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed manoeuvring as well as improved traction, control and confidence for any skill level of rider.
GIDDYUP SUSPENSION DESIGN
We want to make it as easy as possible to experience great rear suspension performance. The GiddyUp suspension system is designed to behave intuitively across a broad range of setup. Because, we get it, sometimes you just want to grab your bike and GiddyUp, without checking your setup. When you do, it will always feel good.
We did this by balancing a 25% progressive leverage curve with a consistent linear rate of change. Anti-squat is tuned to enhance pedalling performance and acceleration. Overall chain growth is moderate and reduces after sag so chain tension doesn't get in the way of the suspension working.
This translates to killer small bump compliance and great mid-stroke support that gradually transitions into an end of stroke ramp that is subtle, yet supportive. The amount of consistent progression is carefully optimized for both air and coil shocks. Riders are able to add or remove volume spacers in air shocks to suite their individual riding style and there is no compromise to bottom out support with coil shocks. The Sentinel has 150mm of rear wheel travel when used with the supplied 205mm x 62.5mm stroke shock. It is also possible to install a shorter, 205mm x 57.5mm stroke shock, to decrease the rear wheel travel to 140mm.
A wide usable sag range of 25 - 35% allows the rider to tune the feel of the bike; from poppy and playful, to planted for ploughing. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.
