The Transition Sentinel was designed for 29er skeptics. A bike so capable, playful and fun that even the most staunch 29er naysayer will instantly convert. With the 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.
