evo.com | Transition Mountain Completes > The new Transition Sentinel Alloy Deore Complete Mountain Bike is a long-term love story between riders and their bikes. Building on the success of Transition's most sought after bike, it has a similar silhouette to its predecessor with subtle tweaks to improve ride performance and kinematics. Its lively geometry mirrors the sporty feel of the Smuggler and Spur, making it more dynamic and playful while maintaining the long travel power and stability you need on rough descents. Available in a sturdy and economic aluminum build, it has everything you need to push yourself to new levels on the trail. Travel 160mm Front (150mm Compatible) / 150mm Rear Geo Adjust Chip The lower shock mount has a geo-adjust flip chip to accommodate mixed wheels, and features a new design that allows water, dirt and debris to easily wash away. Change the attitude of the bike with a simple flip of a chip. High and Low settings give you two very usable geo settings to suit your riding style: High is comparable to most other companies' low settings so there's a high shred warning in effect! Refined Tuning and Kinematics Create a Lively, Progressive Platform The new Sentinel may have a similar silhouette, but Transition have fully redesigned the frame with updated industrial design, features, and geometry to turn it up a notch. The leverage curve supports the bike higher in its travel, leaving plenty of room for big hits while keeping it light on its feet to remain nimble, and quick everywhere else. This gives it the lively, sporty attitude felt in the Spur and Smuggler without sacrificing its capabilities in rougher terrain. New size specific chainstays and a 64 degree headtube angle keep riders balanced with great traction on climbs and descents. All of this creates a bike that encourages new riders to push their limits, while ensuring a seasoned pro feels none.
