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 frame. As a YT, JEFFSY’s mission is to be the most gravity-ready bike of the entire trail bike segment. Therefore, we equipped it up with our award-winning Virtual 4 Link suspension technology which combines excellent off-the-top sensitivity, ample mid-stroke support and a progressive ending stroke. V4L does not only give you the confidence you’ll need for big gaps and rugged terrain but also makes pedaling super efficient and JEFFSY a very effective climber.

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.
