The 2023 Transition Sentinel is a hard-charging 29” trail and enduro bike built for riders who want maximum confidence on steep, technical terrain without sacrificing versatility. Featuring 150mm of rear travel and a 160mm fork, the Sentinel uses Transition’s Speed Balanced Geometry (SBG) for a stable yet agile ride. Its slack 63.6° head angle, steep seat tube, and long reach deliver control on descents and efficiency on climbs. Outfitted with robust components—like Maxxis Assegai and Minion DHR II tires, RaceFace wheels, and SRAM GX Eagle drivetrain—the Sentinel is ready for aggressive trail adventures and enduro racing.

The Sentinel’s geometry and build make it a standout choice for riders seeking a bike that’s equally at home on big mountain descents and long, technical climbs.
