Offering maximum adjustability and aggressive downhill performance, the JEFFSY Pro Race is the first choice for racers, experienced riders, and anybody who hits the trails like they mean it. The high-quality carbon frame is equipped with premium components: FOX FLOAT Factory suspension with kashima-coating, 160 mm front travel and lightweight 27.5" carbon wheels. This makes the JEFFSY Pro Race an uncompromising build for demanding missions.
The Kashima-coated FOX 36 Float Factory fork with 160 mm of travel and FOX Float DPX2 Factory shock are extremely responsive and provide pro-level adjustment possibilities. For the drive train, we’ve chosen the X01 Eagle crank and transmission with an XG-1295 Eagle cassette with 10-50 teeth. This 1x12 drive train provides a wide gear range to ensure that you can put your power down efficiently on any climb.
The great modulation of the SRAM Code RSC brakes translates to optimal control over your speed in any condition. The carbon TRS Race wheels are super stiff and keep the weight low, while the Renthal Fatbar 35 carbon handlebar and the Kashima-coated FOX Transfer Factory dropper post round out the build.

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.
