JEFFSY® CF Pro 27
includes import tax & duty
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 150 mm FOX Performance Elite suspension series wants for nothing, even compared to the Factory version. The reason being that they both use the exact same damping cartridge which provides top-class responsiveness and lots of control on aggressive downhill sections. In fact, the only difference between the Performance Elite version and big brother the Factory Series are the hard anodized stanchions. SRAM’s new Eagle transmission gives you 12 gears and such a wide range that you will completely forget about the front derailleur. For the first time, this year’s YT Range features the new Race Face Turbine dropper post, in different lengths depending on frame size. Maxxis High Roller II tires offer great traction to make sure you get all your horse power to the ground. Weighing in at just 12.6 kg, the JEFFSY CF Pro is no stranger to going fast – and should you ever get in over your head, SRAM’s Guide RSC brakes are standing by to let you drop the anchors at a moment’s notice.
