JEFFSY® AL One 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!
The hydro-formed aluminum frame of the JEFFSY AL impresses with a compact silhouette which is visually very close to the JEFFSY CF. The aggressive headtube angle, low stand over height and the compact chain stays, which are optimized for each frame size, all contribute to creating a 29er that does not handle like a typical big wheeler. Thanks to the integrated Flip Chip, JEFFSY adapts to different terrain with ease: in the Low setting the head angle is more aggressive and the BB drop more pronounced, perfect for fast and rough descending. In the High position you gain ground clearance and agility for slicing and dicing your way through the woods.
Our V4L suspension technology has proven itself beyond any doubt on our gravity bikes, now here it is for the first time on a trail bike. V4L provides sensitive suspension action with perfect mid-stroke support and bottom out resistance. This does not only give you the confidence needed for big gaps and rugged terrain but also makes pedaling a lot more efficient. And similarly to the JEFFSY CF, the aluminum frame’s tube walls have been made thicker where required, to make sure they can withstand the forces generated in critical areas.
The JEFFSY AL One gets a full complement of dependable parts: the RockShox Pike RC and Monarch RT let you relax through gnarly sections, and they have your back for racing, too. SRAM’s X1 drivetrain ensures smooth shifting and the Guide RS brakes slow you right down when things get out of hand. The 2.4“ wide tires from Onza not only look good but they deliver on their promises through the rough stuff too. The JEFFSY AL One is a pure trail weapon that will also leave you some spare change in your pocket for your next bike holidays.
