Summary
The Transition Sentinel is a versatile and lively enduro bike that excels in a variety of terrains, offering a balanced and intuitive handling experience. Its well-tuned suspension and composed nature at speed make it a reliable choice for aggressive riders, though it may require an active riding style to fully exploit its capabilities. While it pedals efficiently and climbs well, some riders may find the rear wheel traction and downhill performance areas for improvement.
Versatile and lively trail bike
Well-tuned and smooth suspension
Balanced and intuitive handling
Surprisingly deft climber with satisfying efficiency
Composed bike at speed and free of drama in the steeps
Short cockpit for seated pedaling
Rear end barely uses its travel, generating little traction
Initial acclimation period needed for rear wheel traction
Not the best for outright downhill performance
There are many good trail bikes available today. I’ve tested many of them, and the new Transtition Sentinal is one of the very best.Bicycling
The Transition Sentinel Carbon XT is a bike with a strong character.
The Sentinel is a bit more subtle until you turn up the volume, and then you realize it's just as bad ass, but it's also more fun than the Enduro in lower angle terrain.

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

The Sentinel has always been known as a trail bike that can be bent to fit different categories. The latest version continues the tradition.
Iterative updates result in a polished package
Excellent descending capability with good support
Climbs better than previous generation
Versatile geometry suits a wide range of riding
Smart features: BOOM Box storage, Fidlock base, cable routing options
Multiple build and material options
DT Swiss M 1900 wheels are heavy
Frame-only pricing not the best value

As is stock, it was provided with dual 29" wheels, with the 205mm x 60mm shock giving 150mm of rear wheel travel.

I’m never going to threaten the podium at an enduro race — but the Transition Sentinel made me feel as if I could, and ride as if I should.
Super-nimble ride feel for such a large bike
Improved shock mount
Flip-chip allows for mixed wheel setup
Needs to be locked out to climb well
Might take some work to get the correct sizing
Seat clamp bolt could be recessed for weather protection
