JEFFSY is ready to be your new bro and wingman – together you will be one hell of an awesome team. Whether on your home trails 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 is the epitome of agility and playfulness. And to meet our high design standards we gave it super compact proportions – looks like you and JEFFSY are going to turn quite some heads together.

    With its aggressive headtube angle, low stand over height and compact chain stays 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 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 super 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.

    The JEFFSY CF Two is the right choice if you do not want to give up on a dual chain ring drivetrain. The Shimano XT 2x11 transmission offers a wide range and more gears to choose from. In terms of suspension, the intuitive and user-friendly Pike RCT3 and Deluxe RT3 from RockShox serve up 150 mm of travel front and rear – a powerful combination that is suitable for beginners and racers alike. As for the RockShox Reverb dropper post, the SRAM Guide RS brakes and the Maxxis High Roller II tires, they are reliable companions for any all-mountain adventure.

    JEFFSY is exactly the right choice for extended trail rides, for the high alpine, for rocky, rooty terrain and rowdy descents. With tons of traction JEFFSY takes you up any climb, and when it comes time to descend, JEFFSY is a true weapon on the trail, with lots of gravity potential and appetite for the rough stuff. If your focus is on very aggressive riding and bike park days, you should take a look at our enduro beast, the CAPRA. By the way: Those who like to ride their JEFFSY often and hard should check it for damages after every ride, and comply with maintenance and service intervals. Spend some love and you’ll enjoy good times with your best friend for a long time.
