This is a custom aluminum Transition Sentinel, size large. It is spec'd with a SRAM GX Eagle 12 speed drivetrain, Rockshox Lyrik Select + fork in 160mm travel.
The Sentinel has 150mm rear travel, and will take you just about anywhere your trail adventure wants to go. With this being a custom build, you are grabbing a new Transition with mostly GX build spec parts, for NX build spec pricing. Come and swing a leg over this Sentinel to see it for yourself.
