"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. Case in point: the newly carbon-fibered Sentinel, a 140-millimeter rear travel, 29-inch-wheeled bruiser unapologetically tailored for the steepest and deepest of terrain." Bike Mag 1/2018

"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 1/2018
