YT Jeffsy 27 CF Pro Bike - 2019

The new JEFFSY makes light work of both the climbs and the downhills. With 150 mm of RockShox suspension, the JEFFSY 27 CF Pro will lure you out of your comfort zone and let you attack even unknown trails with confidence. The generous reach and slack headangle give you a sense of security and ensure reliable handling even in rough terrain. The V4L kinematics provide ample mid-stroke support and plenty of end-stroke progressivity, begging you to get airborne. The compact chainstays and the 27“ wheels give JEFFSY its playful character and help you navigate the tightest of turns with ease. To ensure consistent handling across all the frame sizes, we made the chainstays longer on the XL and XXL. The result: JEFFSY lets you truly redefine your riding style. The JEFFSY 27 CF Pro boasts impressive specifications: the progressive feel of the RockShox Pike RCT3 and the RockShox Super 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. 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.
