Transition Sentinel Alloy

The updated 64-degree headtube angle and size-specific chainstays significantly improve traction and stability on steep climbs. By keeping the bike higher in its travel, the new leverage curve prevents the bike from feeling sluggish or wallowy when you are pedaling through technical terrain.

No, the B.O.O.M. Box internal frame storage is currently exclusive to the carbon version of the Sentinel. This alloy model focuses on a robust, reliable frame construction without the internal downtube storage compartment.

The Sentinel is designed as an aggressive trail bike that bridges the gap between a nimble trail machine and a full-blown enduro rig. It is ideal for riders who want one bike capable of handling big jumps and rough descents while remaining efficient enough for long days in the saddle.

The M6120s are 4-piston brakes, which provide excellent stopping power and heat management for aggressive riding. They offer a reliable, consistent feel that is more than capable of handling sustained, steep descents without fading.

Size-specific chainstays ensure that the bike's handling characteristics remain consistent across the entire size range. By adjusting the rear center length for each frame size, Transition ensures that taller riders don't feel like they are riding a bike that is too short in the rear, while shorter riders maintain a balanced, poppy feel.
