The Sentinel was designed for 29er skeptics. A bike so capable, playful and fun that even the most staunch 29er naysayer will instantly convert. With our reverse mullet suspension configuration, the Sentinel stays responsive and playful while delivering incredible downhill monster truck capabilities. Our Speed Balanced Geometry is the crown jewel that unlocks 100% of the potential of this bike. With SBG you get improved climbing and cornering traction along with incredible composure and control that won't flinch when you open it up on steep, fast, technical descents.

"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.

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