The silhouette might be familiar, but the new Sentinel has had a ground up rebuild, new specs and a host of modifications to make our favourite Transition even better. A Transition Sentinel is an excellent choice for all round riding in Scotland. It's reasonably light, climbs well, and the build is burly enough to easily cope with our descents without making more chilled trails boring. It's tough to think of a better enduro bike on the market right now. New to the line-up, the alloy Deore bike has ROCKSHOX new Psylo fork. Similar to the Lyrik, this fork has 35mm stanchions to suit the nature and intended use of the Sentinel. Other spec highlights include no nonsense, dependable Shimano Deore 4 piston brakes and drivetrain. Transition have also specced dropper posts with sizes increasing with frame size.
