Get up any climb with ease, hit all the jumps on the way down and leave boring behind! The JEFFSY Comp is a playful mix: lightweight carbon frame, reliable 27.5-inch wheels and carefully selected components come together to create an all-mountain bike that feels at home on every trail, from after-work rides to weekend epics.
With 160 mm of travel, the FOX FLOAT 36 Rhythm fork supplies enough reserves for aggressive trail riding. The FOX FLOAT DPX2 Performance shock offers sensitive response with ample ground feedback, and can be adjusted to suit almost any terrain. The transmission is built on NX Eagle: it is based on the same technology as the X01 Eagle group and the 12-speed, 11 – 50 t cassette offers smooth shifting in any circumstances.
The SRAM Guide R brakes score points with great modulation to allow you to control your speed at all times. The TRS Base wheels from e*thirteen in combination with Minion DHR II tires from MAXXIS ensure optimal traction and grip, while the YT Postman dropper post makes sure your saddle is always exactly where you need it.

The JEFFSY 27’s long reach, slack head angle and low front all provide for aggressive downhill performance and a feeling of safety even on the most demanding descents. JEFFSY sits down into the trail, and the low center of gravity puts the rider in the best position for optimal control, even when things get steeper and faster.
The steep seat tube angle provides for efficient uphill performance and the short chainstays help balance out the long main triangle. Thanks to the Flip Chip you can easily modify the geometry by making both the seat tube angle and the head angle 0.5 degrees steeper while raising the BB by 8 mm.
