Intense Primer

At first glance, the new Primer may resemble its predecessors, but the real magic lies beneath the surface. This latest iteration delivers unmatched performance with a reinforced carbon fiber layup and a newly redesigned, externally mounted top link. The wider top link enhances frame stiffness, providing a more responsive and confident ride on the trail. With 150mm front and 150mm rear travel, the Primer is engineered to excel on every trail, offering pure perfection with every ride. We’ve reimagined our classic Primer to deliver the ultimate trail bike for 2025. Striking the perfect balance between stiffness and compliance is a craft we’ve mastered, optimizing the carbon lay-up to increase lateral stiffness around the bottom bracket while maintaining vertical compliance for a smoother, more controlled ride. The updated geometry features a steeper seat tube angle and longer reach, aligning with modern trail standards. We’ve also enhanced the rear triangle, which now comes standard with UDH that is T-Type compatibile. To complete the package, we partnered with FOX and Rockshox to custom-tune the rear shock, ensuring seamless integration with our JS Tuned Suspension Design. Paired with 150mm front travel and 150mm rear, the Primer is ready to tackle any trail with confidence and precision.
