JEFFSY Core 4 - why you want it.
YT cut no corners for the highest CORE level - these uncompromising Factory Team level packages were made for taking on the most demanding terrain. The JEFFSY CORE IV are equipped with the absolute best components and every little detail has been optimized for performance - from the high-end parts to the top-notch carbon frame. The suspension elements are fully adjustable to ensure that even the gnarliest trails are within your comfort zone. From the racetrack to the home trails, these bikes leave nothing to be desired - but that also means that there are no more excuses

Kit Level - Maximal adjustability for uncompromised riding
The JEFFSY Core 4 boasts a FOX Factory Team Level package and seeks riders looking to pin it on every ride. This bike is equipped with a lighter high modulus carbon frame available in the colorways 'Vlad Red' and 'Black Magic'. Thanks to the highly adjustable dream team of the FOX 36 Float Factory fork and FOX Float DPX2 Factory rear shock, riders can rely on 150mm travel front and rear. This flagship model delivers fantastic performance uphill and precise gear shifting thanks to the SRAM X01 Eagle drivetrain with an extended 520% range. SRAM G2 RSC brakes with Centerline rotors (200mm/200mm) deliver maximum braking power and perfect modulation.

Geometry you can't overlook
The JEFFSY Core 4 and JEFFSY Core 3 come with 29-inch wheels and high-performance carbon frames.
All models are available in frame sizes S to XXL with a fun-loving DNA and geometry, which can be adjusted thanks to the Flip Chip, which drops the bottom bracket by 8 mm and results in a 0.5-slacker head and seat tube angle. The slack head angle, long reach and low front give riders a comfortably aggressive position on the bike during technical descents and plenty of control, while the steep seat tube angle allows for great climbing characteristics.
