SENTINEL ALLOY NX



If funds are tight but you desire the performance in our higher priced bikes, the Sentinel Alloy NX won't disappoint. Suspension duties are handled by Rockshox suspension that we meticulously tested and tuned to perform like our higher priced options. A complete NX Eagle gets you the same massive gear range you see on GX and XO1 Eagle to get you up and down with little effort. Finally, we give you a KS Lev Integra dropper post and Maxxis Minion Dual tires so no need to upgrade anything out of the box.

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 maneuvering as well as improved traction, control and confidence for any skill level of rider.

GIDDYUP 2.0HH SUSPENSION

Take our successful GiddyUp suspension system, add one part increased pedaling efficiency, two parts wider sag range, and three parts increased small bump sensitivity, and you get GiddyUp 2.0HH. Incredible pedaling performance balanced with a superb neutral, comfortable and fun feel that we're known for.

We specifically tuned the suspension with a moderate amount of chain growth which is highest at the sag point and decreasing deeper into the travel. Because of this finely tuned wheel path, there is a notable increase in traction when climbing, without the rider noticing the chain growth fighting the suspension movement.

GiddyUp 2.0HH is extremely easy to setup and it provides excellent support throughout the entire stroke of the shock so you can use all your travel without worrying about bottom out. Designed to be active while climbing, rear shock climbing platforms are not necessary. The suspension remains free to smooth out the trail, improve traction and control without sacrificing efficiency. With GiddyUp 2.0HH you can focus on the trail, no remotes, levers or knobs. Just grab your bike and GiddyUp.




"It has a balanced riding position, great traction and isn't a handful in the tight stuff. The Sentinel really benefits from being ridden hard, 'the faster this bike is pushed the more you get from it' were notes from our tester Ieuan after reviewing this bike." - Dirt 100 - Click here for the full article


"This bike appears to be the future of MTB. It was not so long ago we dreamed of a bike that had the capability of speed, handling, descending and climbing. A bike you could take out of the shed and do it all; ride it one weekend and race it the next. Well people, this is the real deal and no doubt one of the most capable all-round speed machines we have tested." - Revolution Magazine - Click here for the full review


"If there's a design-focused arms race occurring in mountain biking, one needs look no further than Transition as a key protagonist in the current push toward ever-longer and more-aggressive geometry. it should come as absolutely no surprise that the Sentinel is most at home bombing downhill. It does this ridiculously well, straight-lining the roughest, ugliest, sketchiest descents with a supreme confidence that borders on disdain." - The Bike Bible Review - Click here for the full review


"The Sentinel is an absolute beast when it comes time to descend, a downright monster when the trail turns steep and rough. There are plenty of long-travel 29ers out there that can handle the Whistler Bike Park, but when it comes to tackling the steepest, chunkiest trails there aren't many that can match the Sentinel's performance.
