There’s a new kid on the block. Say hello to the all-new JEFFSY PRIMUS 27, an aggressive ride for riders between 156 - 165cm. More than just a bike for pint-sized rippers, the PRIMUS 27 is the real deal, and with 150mm of travel and a bombproof aluminum frame, it’s every bit as shreddable as our adult range. From the bike park to epic backcountry adventures, and from that first taste of airtime to the biggest sends at the jump spot, there’s no stopping this ride; it’s a do-it-all weapon built with Young Talents in mind.
Right down to the smallest detail, this bike will see riders crush their goals and skyrocket their skills. RockShox air suspension, a 12-speed drivetrain, powerful four-piston brakes, and durable SUNRinglé Duroc 35 wheels – there are no half-measures here! The PRIMUS 27 inspires confidence and eats burly features for breakfast, making it the ultimate choice to kickstart your young rider’s MTB journey.

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.
