The Primer Factory is the top-spec version of our fast, efficient and highly capable trail-eating 130mm 29er. Truly a professional-level bike, the Primer Factory is designed to offer unrivalled performance and an exquisite ride experience for racers looking for every edge or riders who care about the details of going fast.

Built around our super light SL frame, the Primer Factory frame saves weight on the Foundation and Expert models, featuring full uni-directional carbon monocoque front and rear triangles and a carbon top link. The superior quality frame is finished with internal routing, titanium hardware and integrated chainstay and BB flack guards.

Only the very finest, high-performance components have been specced on the Primer Factory including ENVE carbon wheels and cockpit, SRAM XX1 Eagle drivetrain, Shimano XTR brakes and RockShox suspension. It's all designed to build a package you can roll onto the trails and race seriously fast, while turning heads too.

The high-performance RockShox Pike RCT3 29 Solo Air fork and RockShox Monarch RT3 shock will be tuned specifically for you by our own Intense mechanics so you can get straight out on your new bike and ride with confidence.

Intense Primer

The Primer is a fast trail 29er that can do it all. Most at home on natural singletrack, rocky trail centre descents and technical climbs, it's ideal for the majority of UK trails.

Shorter chainstays, a slack head angle and steeper seat tube create an aggressive, expertly balanced geometry. This makes the Primer feels like it has more than its 130mm of JS Tuned travel, so it can take on all but the gnarliest and steepest terrain.

Whatever you throw at it, the Primer is the most capable, sprightly and playful trail 29er you're likely to throw your leg over.

If you're looking for one versatile bike in your quiver that almost as fast going uphill as it is down, it has to be the Primer.

As with all our JS Tuned bikes, we've carefully selected the component spec for the Primer Factory to give you maximum performance at this bike level.
