The new JEFFSY 29 is easy rolling, efficient, stable and not in the least sluggish. The reason is the well balanced geometry with short chainstays that places you in the center of the bike. This way you’ll make optimal use of the big wheels, and you’ll be surprised at just how agile this 29er is. The large contact patch of the tire provides impressive grip and efficient traction, which you will enjoy on longer adventures as well as in uneven terrain. At the same time, the big wheel keeps you on track even on rough and technical trails and provide you with a sense of security as the speed picks up.
With 140 mm of travel, not only can you and JEFFSY 29 rack up the kilometers but you’ll happily step out together in the bike park as well. 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.
The JEFFSY 29 CF Pro boasts impressive specifications: the progressive feel of the 140 mm RockShox Pike RCT3 and the RockShox Deluxe RT3 shock ensures you have full control even during big impacts, providing enough travel reserve to deal with fast and rough downhill sections.
SRAM’s wide range GX Eagle drive train offers 12 gears and with 10–50 teeth on the cassette you can tackle both steep climbs and high-speed descents with ease. Because it’s never about pure speed but rather perfect speed, SRAM’s Guide RS brakes give you precise control and reliable stopping power, while e*thirteen‘s TRSr tires deliver superior traction and rolling speed.

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.
