Transition Sentinel Top Tier Build

Ride what the pros ride with the Sentinel Carbon AXS build kit featuring a dominating list of components. At the forefront of the Carbon AXS build is the tried and true high-performing SRAM GX Eagle AXS drivetrain that can handle impact, shift under load, and is fully waterproof. The Sentinel Carbon AXS drivetrain simplifies your riding experience with wireless shifting and a worry-free design; the SRAM AXS app allows you to customize your shifting response and keep an eye on the battery life of your drivetrain.

The Sentinel Carbon AXS build kit features OneUp bars and a OneUp Dropper post with an extra-long seat post insertion to get your seat out of the way when the trail gets steep. An ANVL stem and an ANVL saddle are designed to perfectly complement Transition’s bikes, designed in house, to keep up with hard-charging riders and the playful character of bikes like the Sentinel.

The Carbon AXS build kit tips just over 31 pounds, even with the beefy enduro Maxxis Assegai and Minion tires. You’ll have ample traction through loose and loamy forests or racing through sandy corners.

FOX Factory suspension is designed by and for pros. The Sentinel Carbon AXS comes stock with a FOX Float X2 Factory shock, offering coil-like compliance for plush performance. Paired with a FOX Float 36 Factory 160mm fork, the Sentinel upholds a high level of responsiveness.
