JEFFSY is ready to be your new bro and wingman. You’re going to be the new dream team. Whether on your hometrails or crossing high mountains, JEFFSY scales the toughest peaks with unbelievable drive and traction, and inspires you to unexpected performances. JEFFSY lets you discover the most remote locations, climb the highest peaks, and keep it pinned on the way back down. Because JEFFSY is the YT of All Mountain bikes, it won’t hold you back even in the roughest terrain. Thanks to its gravity oriented geometry JEFFSY remains agile and playful, even with the 29” wheels. And to meet our high design standards we gave JEFFSY super compact proportions – you two are going to get a lot of looks!
JEFFSY’s voluminous but light full carbon frame and its compact silhouette already have some observers doubting whether they are actually looking at a 29er. With its aggressive headtube angle, low standover height and compact chainstays JEFFSY is a player among trail bikes, ready to go fast and get loose in the roughest of terrain. The length of the rear triangle comes optimized for each frame size and ensures a completely new and atypical handling for a 29er.
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 fast and rowdy 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 chainstays out of harm’s way when the action heats up.
The standout highlights of our top of the line model are the DT Swiss carbon wheels and the FOX suspension components consisting of the FOX Float DPS Factory shock and the FOX 34 Float Factory fork. The 780mm wide carbon handlebar and carbon cranks complete this high end build. With SRAM’s X01 transmission you shift precisely, easily, and silently, and should things get a little hectic, the Guide Ultimate brakes slow you down with authority. The JEFFSY CF Pro is the no-holds-barred bike for riders who accept no compromises.
