The alloy rear triangle offers great sensitivity, delivers good progression when it matters and gives you a lot of pop to let you give into your more playful instincts. The generous reach, slack headangle and 150 mm of travel make for a quick and stable ride on the descents. The low standover height and the compact chainstays optimize the handling and ensure agility even in demanding terrain.
As a true all-mountain bike JEFFSY also performs on the climbs: the rear suspension is practically bob-free and the steep seat tube angle lets you gain the summit with ease. To ensure consistent handling across all the frame sizes and to make sure you feel right at home on your JEFFSY, we made the chainstays longer on the XL and XXL. The result: JEFFSY lets you truly redefine your riding style.
Aside from the missing Kashima coating, the 150 mm FOX 34 Float Performance Elite fork and the FOX Float DPS Performance Elite shock want for nothing in terms of performance when compared to the Factory versions. The reason for this are the near-identical damping cartridges which offer excellent responsiveness and enough adjustability to satisfy even the most demanding of racers.
Equipped with Shadow+ technology, Shimano’s easy-shifting XT rear derailleur presents a low profile and reduces chainslap for a quiet and serene riding experience. The shifting performance of the e*thirteen cassette ensures even more fun on the trail: with 9–46 teeth it provides crisp shifting and enough range to tackle both climbing and decending. SRAM’s Guide R brakes with proven 4-pot calipers slow you down reliably and with good modulation, while e*thirteen’s TRS wheels and tires give you the best possible grip.

Progress means change. In the case of the new JEFFSY 27, the changes are relatively small but the improvements are still noticeable. For an even better ride, we have given the new JEFFSY 27 longer reach and a slacker headangle. This has a calming effect on the bike and gives you more control when things get steeper and faster, the long reach helping JEFFSY stay on track and making sure even taller riders can sit “in” the bike.
To apply YT’s Tailor Made concept also to the new JEFFSY, we’ve significantly shortened the seat tube and introduced an XXL size. This gives you the choice between two or even three frame size in order to adapt the reach measurement to your riding style and preferences. To ensure consistent handling across the frame sizes, we’ve made the chainstays longer on the XL and XXL, while the integrated Flip Chip lets you further adapt the bike’s geometry to suit your technique and terrain. Run it in the low position to slacken the headangle and lower the BB for fast and rough terrain, or switch to the high position to raise the BB for better clearance and more fun on the climbs.
