Junior Sizing, Big Capabilities
The JEFFSY PRIMUS - no stuffing around, no bedtime stories - but a real MTB for motivated young riders. In function and handling, it's as capable as its big brother JEFFSY, but in a smaller size. Whether you're headed out for an enduro loop, a day in the bike park, or a jump line session, the JEFFSY PRIMUS lets you go big regardless of how big you are. Get some little shredders!

Discover Your YT
It's never too late to try something new and find your passion. That's hardwired into the YT brand, and every bike that they make. Young Talent is what YT stands for. It's inside us all. It's up to each of us to find our young and undiscovered talent, to overcome conventions and pursue our dreams.

JEFFSY PRIMUS 26 - why you want it.
The JEFFSY PRIMUS 26 wants you to get out there and discover the world. Specifically developed for riders between 145 cm and 160 cm, its playful character and robust aluminum frame make it a keen partner for having fun. Whether you're on flowy trails, a long ride, or heading to the bike park to shred, uncompromising components such as the 140 mm Manitou Machete fork and the custom-tuned RockShox Deluxe Select+ shock will have your back anywhere.

A kit that makes you look twice
The machete from the Manitou is the perfect fork for junior enduro riders. Equipped with robust, anodized stanchions, the characteristic "Reverse Arch" design reduces the weight without compromising rigidity and provides excellent cushioning for lighter-weight riders. The air chamber volume has been specially tuned for the Jeffsy to help prevent bottom-outs even with a softer set-up. Adjustable air pressure and rebound allow the damper to adapt quickly to the needs of the trail. SX Eagle is the starting point for SRAM's proven mountain bike technology. Features like X-Sync and homogenous gaps between gears give this carefree package intuitive operation and long-lasting durability. Proven technology with classic YT design. This hydraulic dropper post with stealth mechanics and cable routing has an anodized, scratchproof body. Lasered markings simplify saddle height set-up and the left-hand mounted remote operates effortlessly.
Geometry you can't overlook
The JEFFSY PRIMUS JP 26 is made for riders between 145 cm to 160 cm and built around a 140 mm travel fork. Thanks to the slack head angle, the bike feels confident and stable, giving you noticeable control when the terrain gets rough and steep. At the same time, short chainstays maintain a good balance for smaller riders and provide for a playful riding feel without losing the planted character of the bike. The low seat height guarantees a comfortable position on the bike and allows you to move it around with ease and style. Additionally, thanks to the integrated Flip Chip, the geometry of the JEFFSY PRIMUS JP 26 can be adjusted to suit your riding style and your terrain.

Flip Chip
Thanks to the Flip Chip, the frame's geometry can easily be adapted to your riding style. In the low position, the head angle is slacker and the BB drop more pronounced, for better stability when pinning it in rough terrain. In the high position, the steeper head angle and higher BB position make for easier climbing and more agility on tighter trails.

Superior Frame Protection
Perfectly integrated guards protect the frame against rock impacts and scratches. 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 in this critical area. The chain stay and seat stay guards also help keep the noise down, so that the only sound you'll hear on the trail is that braaaaap! we all love so much.

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 and help prolong the service life of your bike.

Internal cable routing
For optimal protection, all cables are almost completely routed through the frame. Integrated cable ports and a single cable clamp hidden under the rear linkage help create a super clean look. Uninterrupted internal tubes and the single clamp system provide for easy cable replacement.

Single sided hardware access
MOB-Pit approved: the suspension linkage and rear triangle hardware can be installed and removed from one single side, which makes working on the bike easier and faster and gives the bike a cleaner look.

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 chain stay and seat stay guards help prevent unwanted noise from the drivetrain.

Integrated chainsuck protection
Should things get a little rough, the inconspicuous chain suck plates protect the frame from damage caused by a dropped chain. This keeps sensitive areas out of harm's way and helps prolong your frame's service life.

Virtual Four Link / V4L
V4L is responsible for providing outstanding small bump compliance that virtually sucks you to the ground as well as great midstroke support to really optimize the use of the available travel. And the nice pop makes sure you can get airborne at a moment's notice. So you don't bottom out harshly even after hitting the biggest jumps, the ending stroke spring curve is very progressive. V4L supports you around the sag point, ready to absorb obstacles but without being affected by pedalling forces.
