JEFFSY CF Two 29
includes import tax & duty
JEFFSY is ready to be your new bro and wingman. You’re going to be the new dream 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 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 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 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 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.
With the JEFFSY CF Two you get a well-equipped trail bike with a 2x11 drivetrain that gives you a wider range of gears to shift through, so you have no more excuses on the next uphill section. This carbon bike comes with a complete Shimano XT group that is snappy and reliable, as well as a wide Race Face cockpit, a RockShox Reverb Stealth, and sturdy 2.4“ Onza Ibex tires mounted on TRS wheels from e*thirteen.
