The JEFFSY 29 CF Comp is a hybrid: it features a lightweight carbon front triangle combined with a robust aluminum rear triangle. The efficient traction of the big wheels, the central seated position and the neutral behavior of the rear triangle help you get up the hill without wasting energy – you’ll need it when things point downhill again!
The slack headangle, long reach and 140 mm of suspension travel provide a fast and stable ride, while the progressive alloy rear linkage ensures a sensitive suspension action with lots of pop. Additionally, the low standover height and the compact chainstays optimize the handling to let you really take advantage of the 29er wheel. To keep the bike balanced in every size, the chainstays are longer on the XL and XXL. The result: JEFFSY lets you truly redefine your riding style.
Aside from the missing Kashima coating, the 140 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.

For an even better ride feel, the new JEFFSY 29 has a significantly longer reach than its predecessor and on the CF Pro Race model we also gave it 10 mm more travel. The seat tube angle has been made steeper for a more ergonomic seated position, so that even taller riders end up in the center of the bike and can fully benefit from the slack headangle. To apply YT’s Tailor Made concept also to the new JEFFSY 29, 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. The now even slacker headangle has a calming effect on the bike and gives you more control when things get steeper and faster. This is also exactly the point where the longer reach makes itself known, helping JEFFSY stay on track and making sure even taller riders can sit “in” the bike. 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.
