The world of mountain biking is exploding with Young Talent, and the JEFFSY PRIMUS 26 is here to champion it. Developed for riders between 145cm and 160cm tall, it’s a YT through and through and a sure-fire hit with any rising trail superstar. From the shred-ready SRAM drivetrain to the Maxxis Minion tires, there are no compromises here – this is a hard-hitting ride that’s every bit as capable as its big brother JEFFSY!

The RockShox suspension is easily adjustable to suit a range of rider weights and provides 140mm of rut-chomping suspension travel in the front and rear. The sturdy SUNRinglé wheels stay true for overcooked sends and sideways landings, and a 100mm Postman dropper boosts standover for rowdy descending.

Frame

FRAME PROTECTION

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.

Headtube

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.

Internal Cable Routing

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.

Chainsuck protection

The inconspicuous chainsuck plates protect the frame from damage caused by a dropped chain keeping critical areas out of harm's way.

SEALED BEARINGS

Extra seals protect the high-quality, double-sealed full complement bearings to keep water and dirt out and help prolong the service life.

Virtual Four Link

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.
