Transition Sentinel Alloy Frame 2019

Transition Sentinel Alloy Frame 2019 Gunmetal Grey Side
Description

When it comes to the old saying, riding is believing, it couldn't be more true for the Sentinel. This bike will scramble your brain as to how capable it is, how rowdy it can get, yet how composed it is as an all-around trail bike. The Sentinel has amazed critics and earned the title of one of the most downhill attacking long travel 29ers available. But, don't let all that monster truck talk fool you into thinking this is a one trick pony, the Sentinel delivers going up and down thanks to our Speed Balanced Geometry. Sure we could spend days ranting on and on about how much we love this bike and all its technical features, but it would be a lot easier if you just throw a leg on one and take it for a ride.

The Sentinel Alloy frameset is the perfect starting point to create the custom bike that suits your riding style. The heat treated hydroformed alloy frameset is perfect for those who want durability and strength at a great value. The alloy frame shares the exact same geometry and suspension setup as the carbon version. For rear suspension, we worked tirelessly with Fox to create the perfect tune with the extremely impressive DPX2 rear shock. Amazing small bump sensitivity like a coil shock and excellent mid-stroke support and bottom out control. The Sentinel Alloy Frameset features a threaded BB, external rear brake routing for easy brake maintenance, full water bottle storage inside the main triangle, boost rear end and rubber molded frame protection. 

Speed Balanced Geometry
SBG ensures the bike maintains low speed agility, front wheel traction, and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds. With SBG, a slacker head tube angle is combined with a all new reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes. One of SBG's greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed maneuvering as well as improved traction, control and confidence for any skill level of rider.

GIDDYUP 2.0HH SUSPENSION
Take our successful GiddyUp suspension system, add one part increased pedaling efficiency, two parts wider sag range, and three parts increased small bump sensitivity, and you get GiddyUp 2.0HH. Incredible pedaling performance balanced with a superb neutral, comfortable and fun feel that we're known for.

We specifically tuned the suspension with a moderate amount of chain growth which is highest at the sag point and decreasing deeper into the travel. Because of this finely tuned wheel path, there is a notable increase in traction when climbing, without the rider noticing the chain growth fighting the suspension movement.

GiddyUp 2.0HH is extremely easy to setup and it provides excellent support throughout the entire stroke of the shock so you can use all your travel without worrying about bottom out. Designed to be active while climbing, rear shock climbing platforms are not necessary. The suspension remains free to smooth out the trail, improve traction and control without sacrificing efficiency. With GiddyUp 2.0HH you can focus on the trail, no remotes, levers or knobs. Just grab your bike and GiddyUp.
