JEFFSY® 27 CF Pro
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. The result is the perfect balance: you climb effortlessly, you fly through corners, and you even feel right at home when things get rugged, hard, and fast.
The 150mm FOX Float fork and FOX Float DPS shock are equally outstanding in this Performance Elite version as the Factory model. The reason for this is that it uses the same damping cartridge, which offers excellent responsiveness and racing-level adjustability. 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 height adjustment range of the FOX TRANSFER PERFORMANCE ELITE dropper post is infinitely variable, and controlling the post’s return speed as well as making small height adjustments is very easy thanks to the low lever force required. SRAM’s Guide RSC brakes offer the ultimate combination of power and control: the innovative SwingLink technology provides more power, better modulation, shorter lever travel and the best lever feel in the business.

Thanks to the flip chip technology, JEFFSY’s geometry can be perfectly adapted to different terrain and to your style of riding. The low position gives you a more aggressive headtube angle and a bigger BB drop – perfect for quick and grimy downhill sections. The high position provides a smaller BB drop, so you can blast trails and tight turns with more ground clearance. Our prized Virtual 4 Link suspension technology is present on JEFFSY as well; sensitive, progressive, with lots of mid-travel support. This does not only give you the confidence needed for big gaps and rugged terrain but also makes pedaling a lot more efficient. The tube walls are thicker in critical areas to make sure the frame can handle the abuse, and integrated protectors keep the downtube and chain stays out of harm’s way when the action heats up.
