24"/ 26"
SIZE DOESN'T MATTER
Size shouldn’t decide who has the most fun on the trail. That’s why we developed the JEFFSY PRIMUS JP, a potent high-performance bike with 24-inch or 26-inch wheels that fits you like a glove – ride uncaged!
JEFFSY PRIMUS JP 24
Riders between 135 cm and 150 cm go for the JEFFSY PRIMUS JP 24. It is the perfect bike for gravity rookies as we adapted the frame, suspension, and components specifically to the needs of smaller shredders. The shock has been tuned for lighter riders while the handlebar, seat, and seatpost are all size-specific as well, to provide comfort for longer days in the saddle. With 130 mm of travel up front, the bike provides both easy control and enough reserves to deal with rougher descents.
JEFFSY PRIMUS JP 26
Riders between 145 cm and 160 cm shred best with the JEFFSY PRIMUS JP 26. The frame and suspension have been designed specifically to meet the needs of smaller riders and the shock has been custom tuned for lighter body weights. With uncompromising component spec, Flip Chip geometry adjustment and 140 mm of travel up front, the JEFFSY PRIMUS JP 26 is perfectly equipped for bike park sessions as well as longer all-mountain adventures.


Our goal was to develop a playful high-performance bike for smaller shredders. To make sure it also climbs well, we took the JEFFSY 27 as inspiration and adapted the suspension leverage ratio to riders with lower body weight so that you get maximum use out of your suspension in every situation. For the same reason, our V4L rear suspension reacts smoothly and gives you excellent control even in rough terrain.

"For 2020 I want to be as good as I can and have as much fun in the air."
Flip Chip
Situated at the lower shock mount, the Flip Chip makes it quick and easy to adjust the geometry of the JEFFSY PRIMUS JP 26 according to the terrain and your riding style. The Low position provides for a more aggressive head angle and a bigger BB drop, ideal for fast and rough tracks. In the High position, the head angle is 0.5 degrees steeper and the BB is 9 mm higher. The higher BB gives you more ground clearance and more fun on the climbs.
Race-Specific Advanced Sealing Concept, Axial Lip-Seal (RASCAL)
Extra seals protect the high-quality, double-sealed, full complement bearings to keep water and dirt out. This ensures optimal function of your bike over time and helps prolong its service life.
V4L / Virtual Four Link
Our award-winning V4L suspension technology provides great sensitivity and ensures optimal use of travel. The nice pop helps you get airborne whenever you want to, while the end-stroke progressivity makes sure you don’t bottom out even on monster jumps.
Frame Protection
Perfectly integrated polyurethane guards protect the frame against rock impacts and scratches. The chain stay and seat stay guards also help keep the drivetrain noise down on the trail.
Chainsuck Plate Protection
Should things get a little rough, the in the Mech Hanger integrated chain suck plate, protects the frame from damage caused by a dropped chain. This keeps the sensitive area out of harm´s way and helps prolong your frame´s service life.
