True to the trail

The 2020 Primer S Expert offers you the superior grip of a 27.5+ rear wheel with the speed and control of 29" wheel up front. The result is an unmatched trail riding experience with bags of traction and agility, complemented by a great spec offering and top value.  

Completely redesigned from the ground up, the Primer S Expert is exquisitely made from our Optimised Layup carbon boasting a monocoque frame and more rigid dual-strut rear triangle. The bike also makes use of our all-new JS Trail Link carbon top link, which with a turn of the new Flip Chip axle bolt allows you to tweak the Primer's geometry to better suit fast flowy trails or rougher terrain.

The frame is completed with quality detailing including titanium hardware, rattle-free internal shift, brake and dropper cable guides and thicker, broader rubber frame protectors. It's also beautifully painted in rich, crisp colours with decal-free logos for a high-end finish that sets it apart from the competition.

If invincible grip, incredible agility and high-speed control are top of your list, the 2020 Primer S Expert will deliver in spades with astonishing uphill traction, grin widening downhill performance and an aggressive character that'll have you seeking out the toughest lines.

The Primer S also has clearance for a 29" wheel at the back or a 27.5+ at the front, making this trail eater all the more versatile with a quick wheel change.

On the spec side, we've packed the Primer S Expert with high-quality kit that'll help you take your riding to the next level. Highlights include Fox Performance suspension, SRAM NX Eagle 12-speed drivetrain, size-specific dropper posts, E13 LG1 wheels wrapped in Maxxis rubber and Shimano M500 hydraulic brakes.

The high-quality Fox Performance 36 fork and Fox Performance DPX2 shock will be tuned specifically for you by our own Intense Cycles UK mechanics so you can roll onto the trails with confidence from your first ride.

About The Primer S
Intense Primer S

The Primer is our one-bike quiver, 140mm do-everything trail bike with longer, slacker, more aggressive geometry. The Primer offers outstanding, confidence-inspiring rideability built specifically for the trail. Available in three wheel sizes – 27.5”, 29” and the staggered Primer S with its 29” wheel up front and 27.5” at the rear – the Primer range offers something for everyone, each designed to offer exceptional performance. 

A combination of race-inspired development and our dedication to excellence has meant hundreds of hours of prototyping and testing by the Intense team and Intense Factory Racing, resulting in innovative new design features.

The completely revised frame utilises our new JS Trail Link, which perfectly bridges the gap between XC pedalling efficiency and bump compliance of the Enduro link. Using our new Flip Chip geometry, within a few seconds you can transform the Primer’s head tube and seat tube angle, bottom bracket height and suspension – flipping between firmer rear suspension for faster, less technical terrain or maximum suppleness when things get rocky.

We’ve also created a new dual-strut design rear triangle that makes the most of your power while reducing flex for a deft, confidence-inspiring ride experience. Other changes include a threaded bottom bracket for rock solid bearing performance and larger, thicker rubber frame protectors.

Fox suspension maintains our trail-focused approach, while we’ve specced each model carefully to give the right balance of performance at each price point so whether you want a great spec, better spec or the best spec, we’ve got you covered with a bike that’s more than ready to take on the battle of the trails.
