The JEFFSY CORE II will please both beginners and experts alike, with its high-end aluminium frame. These robust bikes are ready for the toughest missions, thanks to high-quality components and uncomplicated suspension elements. Regardless of whether you want to go out for a quick rip or a long bike trip - with the JEFFSY CORE II you'll be ready for anything.

Kit Level - Just get out there and go.
The JEFFSY Core 2 focuses on the necessary ingredients for plenty of GOOD TIMES on any trail. The cold-forged, hydroformed, and double-butted aluminium frame offers extreme durability for riders looking to push the limits or newcomers to this "game of bike". A FOX suspension set-up comprising of the FOX 36 Float Performance fork and FOX Float DPX2 Performance offers either 150 mm travel front and rear with a 29-inch wheel or 160mm with a 27.5-inch wheel. The reliable SRAM NX Eagle drivetrain will get the job done and allows riders to shift gears smoothly and climb efficiently.

Geometry you can't overlook
The JEFFSY Core 2 comes in either 29-inch or 27.5-inch wheel sizes paired with a highly durable aluminium frame.
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.

This bike will be shipped partially built in a box and will require some assembling.
