Unicorn's Do Exist

Why We Love It
The Sentinel is a mid-upper travel 29er steed that will give you confidence to hit lines and features you used to go around. Transition's "SBG" (Speed Balanced Geometry) ensure's the bike feels agile at slow speeds, stable at fast speeds, increases front wheel traction, and ensures proper rider weight distribution. Combine this stellar geometry with Transition's "Collet main pivot technology", which improves rear end stiffness as well as keeping your hardware tight (no one likes discovering missing hardware on their bike). Not just a fair weather rider? Don't worry, Transition has your back there as well with additional pivot bearing shields to keep contamination and moisture out so you can ride worry free. Looking through this bike, it truly feels like Transition has thought of every way to make our lives easier. Threaded bottom brackets, user friendly cable routing, ample tire clearance, frame protection in all the right places, and a gear mount under the top tube are just some of the amazing touches we love about this trail ripper. Its lively, it pops, it climbs, its truly a unicorn in the bike world.
