YT Jeffsy Base Bike - 2020

For the JEFFSY Base, we equipped a robust aluminum frame with carefully selected components. Whether you’re blasting around your home trails or touring the mountains, the RockShox suspension with 160 mm front travel and the playful handling of the 27.5'' wheels ensure that you’ll always have fun. The JEFFSY Base is the perfect bike both for lovers of high-quality aluminum bikes and all-mountain rookies alike. With 160 mm of travel, the RockShox Yari RC is built around the same robust chassis as the Lyrik, matched up here with the proven Motion Control damper. Out back, the RockShox Deluxe Select shock provides all the performance you require from an all-mountain bike. The 1x12 drivetrain is made by SRAM: the SX Eagle group features an aluminum crank with a steel chainring and thanks to the 11– 50 t cassette, it provides enough range to make sure you can always find the right gear for any terrain. The M1900 wheels from DT Swiss were developed specifically to meet the demands of modern all-mountain bikes and together with the MAXXIS Minion DHR II tires they form the perfect combo for both uphill and downhill action. SRAM’s Guide T delivers reliable braking performance while the YT Postman dropper post makes sure you always have the saddle where you need it. The JEFFSY 27’s long reach, slack head angle and low front all provide for aggressive downhill performance and a feeling of safety even on the most demanding descents. JEFFSY sits down into the trail, and the low center of gravity puts the rider in the best position for optimal control, even when things get steeper and faster. The steep seat tube angle provides for efficient uphill performance and the short chainstays help balance out the long main triangle. Thanks to the Flip Chip you can easily modify the geometry by making both the seat tube angle and the head angle 0.5 degrees steeper while raising the BB by 8 mm.
