With the playful JEFFSY Pro you have fun on every trail: excellent climbing performance helps you get up the hill, while the balanced geometry and rad ride feel let you really enjoy those fast downhill sections. We have equipped the lightweight carbon frame with high-performance components, RockShox suspension with 160 mm front travel and 27.5'' wheels to let you leave the daily grind behind.
The 160 mm travel Pike Select+ RC from RockShox offers adjustable low-speed compression and provides even better control on the trail thanks to the all-new Charger 2.1 damper. Out back, the RockShox Super Deluxe Select shock features the highly adjustable DebonAir airspring as well as the damping characteristics you expect from an all-mountain bike.
To help you manage both demanding climbs as well as fast descents, the wide-range SRAM GX Eagle drive train provides 12 gears across a 10 – 50 t cassette, while the proven SRAM G2 RSC brakes slow your bike down with authority when you need it. The reliable TRS Plus wheels from e*thirteen together with Minion DHR II tires from MAXXIS provide superior grip and help give the JEFFSY its great rolling characteristics.

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.
