Far out or nothing – JEFFSY® represents our very own definition of trail riding. With gravity DNA, JEFFSY is the most aggressive all-mountain bike on the market, the YT amongst trail bikes, perfect for all those of you who want to ride a tad faster, more aggressive and more creative than everybody else. The frame scores points with a compact silhouette, an undoubtedly gravity-inspired geometry and one of the most aggressive headtube angles to be found on any trail bike today. The low stand over height, distinctive reach, wide riser handlebar and compact chain stays ensure optimal handling. And because we make no compromises, the length of the rear triangle is optimized for each frame size, which helps create a bike that does not handle like a typical 29er. The result is the perfect balance: you climb effortlessly, you fly through corners, and you feel right at home when things get gnarly, hard, and fast.
The 140mm FOX 34 FLOAT RHYTHM fork and the FOX DPS PERFORMANCE shock combine to form a high-level suspension solution. The fork’s GRIP cartridge features a 2-level compression adjustment which raises the performance bar in this segment. The new 1x11 e*thirteen TRS+ cassette boasting a 511% gear range, outperforms traditional 12-speed transmissions by 11%, is much easier to adjust and distinctly more durable. With its 9-46 teeth sprockets it’s the first choice when it comes to aggressive trail riding and rough race runs. The e*thirteen TRS+ dropper post with a remote lever shaped like a shifter offers four preset seatpost height positions that with super smooth adjustment. The SRAM Guide R brakes with a proven four-piston caliper delivers power and good modulation, while the lever offers adjustable reach.
