Intense Primer 2019

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 Foundation to give you the best possible performance at this bike level.
