Résumé

The Transition Sentinel is celebrated for its robust downhill performance, precise handling, and progressive rear suspension that excels in generating traction. Its updates, including a redesigned chainstay protector and integrated BOOM Box storage, enhance its modern appeal. While it climbs comfortably, it may require locking out the rear shock for optimal efficiency on technical uphills. The Sentinel's versatility and aggressive geometry make it a standout in the enduro category, rewarding riders with control and precision on challenging terrain.

[First Ride] Transition Sentinel V3

oct. 2024 · Ian Collins

In July I attended the launch of a new bike which I’ve given very high praise in its past iteration – the Transition Sentinel. Now in its third time around, the already highly versatile rig boasts updated geometry and improved kinematics as well as downtube storage, fully internal cable routing and a flip chip. I managed to get a few solid rides in on the new bike deep in the middle of Summer. Luckily, that coincided with a one-off rain storm that revitalized the local soil during an atypically dry Summer in Bellingham, Washington. The trails I rode included all
