If you're looking for the best parts you can get for a great price, our sentinel alloy GX will tick every box. We know suspension performance is king so we give you the same Fox fork and rear shock we spec on our top of the line sentinel carbon xo1. The drivetrain is GX eagle with a massive gear range that is the new standard for performance and value. Along with top of the line suspension, we give you killer 4 piston code rsc brakes that are a crowd favorite here at transition. We finish the build with rock-solid stans flow s1 team complete wheelset and the best maxxis minion 3c tires you can buy. The sentinel alloy GX is a true riders bike that wants top performing parts that can appreciate a tried and true alloy frameset that can charge all day.
Available colours: pinot noir red, gunmetal grey
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.
