Playful, fast, and infinitely fun, the JEFFSY PRIMUS 24 is a hard-hitting MTB for up-and-coming shredders between 135cm and 150cm tall. Wherever you ride, this bike brings the Good Times; technical descents, heavy sends, and formidable climbs, it does it all, and it’s built tough to go the distance.
The lightweight aluminum frame is ultra-durable and equipped with the same quality components found on our adult bikes, including adjustable air suspension and confidence-inspiring four-piston brakes, alongside Maxxis tires for endless traction on loose terrain. Grip it and rip it! The PRIMUS 24 features an SDG Slater cockpit with a reduced-diameter handlebar and grips to fit smaller hands and enhance control.

Forged, multi-butted and hydro-formed high quality aluminum ensures that the frame is not only light but also extremely strong.

Made from super-tough and wear-resistant PA 66, the downtube protector is bolted on and can be easily replaced. It is designed to wrap around the bottom bracket and thus provide extra protection for the side walls of the downtube from impacts and scratches. Additionally, the rubber chainstay and seatstay guards help prevent unwanted noise from the drivetrain.
To optimize the weight to performance ratio, the contact surfaces for the integrated headset are pre-formed directly in the frame. Additionally, the ZeroStack design ensures a high level of durability thanks to the integrated bearing shells.
For optimal protection, all cables are routed almost completely through the frame. They are guided through the chainstay with internal cable tubes, while they are wrapped in foam as they pass through the main frame to reduce weight and at the same time prevent noise. All cable ports are protected against the ingress of dirt and water with cable plugs. Additionally, the cables are secured on the head tube with cable clamps and they are routed over the main pivot to prevent chafing.
The inconspicuous chainsuck plates protect the frame from damage caused by a dropped chain keeping critical areas out of harm's way.
Extra seals protect the high-quality, double-sealed full complement bearings to keep water and dirt out and help prolong the service life.
Our award-winning V4L suspension technology provides sensitivity off the top, with good mid-stroke support and plenty of end-stroke progressivity. The nice pop helps get the bike airborne whenever wanted, while the end-stroke progressivity makes sure the rear shock doesn't bottom out even on monster jumps. The high amount of anti-squat keeps the rear suspension neutral and improves pedal efficiency.
