With the new JEFFSY 29 you’ll finally be able to ride every trail the way you always wanted to. Every detail on the range-topping JEFFSY 29 CF Pro Race is designed for pure performance and the high-quality spec makes it the first choice for racers and experienced pro riders alike. Thanks to the big 29” wheels, 150 mm of travel and a lightweight component spec it is the perfect partner for anything from flowy home trails to long backcountry adventures.

With good rolling speed, incredible traction and impressive climbing abilities the JEFFSY 29 is ready to bring you up any mountain. After that, you’ll be ready to chase your personal records on the way back down, because once they get moving, those 29er wheels roll easily and quickly over rocks and roots. Additionally, the slack headangle ensures calm and composed handling when the speed picks up. V4L suspension technology is supple off the top and supports you around the sag point, with enough pop and progressive travel reserves to make sure you don’t bottom out needlessly even on bigger jumps. The result: JEFFSY lets you truly redefine your riding style.

With a no-compromise component spec, the JEFFSY 29 CF Pro Race is the prime choice for racers and experienced pro riders alike. The FOX 36 Float Factory fork with 150 mm of travel and FOX Float DPX2 Factory shock are extremely responsive and provide pro-level adjustment possibilities. The stiff TRSr crank gives the drive train a direct feel, while Shimano‘s crisp and precise XTR shifting ensures you are always in the right gear to put the power down on the trail.

The awesome modulation of SRAM‘s Guide RSC brakes helps you stay in control even on steep slopes and in tight turns, while the stiff Renthal Fatbar Carbon and Renthal Apex cockpit combo lets you steer your bike with confidence. FOX’s Kashima-coated Transfer Factory dropper post provides stepless height adjustment to let you put your saddle exactly where you need it to be.

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.
