The Sentinel is a bit of a do-everything bike in the Transition range, up for all-dayers in the hills or uplift days.
Out the box, the bike is set up with a 150 mm Kashima Fox X2 shock, but you can change the rear shock for a shorter one to run the back at 140 mm. The frame will be happy with a fork between 140 and 160 mm.
Transition have given the longer-lower-slacker approach a name – “Speed Balanced Geometry” – but effectively it means a longer top tube and slack head angle, ready to run a short stem and short offset (42-44 mm) fork. All sizes can take a water bottle, though you’ll need to use a fidlock bottle on the size small frame.
Never ones to shy away from a cheesy name, the Transition’s “GiddyUp” suspension has fantastic small bump sensitivity and enough progression to run a coil shock without blowing through the travel. The Enduro MAX bearings and additional bearing shields are a huge plus point for UK riding.
