We started with a clean sheet and no constraints.
In developing the Saker we identified the following characteristics that would be fundamental in achieving our vision.
- A rearward rear axle path to absorb impacts from rough terrain and increase ability to carry speed.
- 100% Anti squat characteristic for pedal efficiency.
- Removal of chain tension feedback and interference.
- A progressive rear shock rate, to maximise grip and maintain composure through big hits and drops.
- Stable geometry and balanced weight distribution.

Producing the ultimate 160mm travel mountain bike, something that creates a new benchmark, is no easy task when you look at many of the products on the market. Yet everything has short falls and compromises, everything can be improved. We felt there was an opportunity to combine a series of features to gain performance.
Each design element was selected to work in unison. Our suspension design is defined by the term ‘HIPR’ which refers to combination of design elements. ‘HIPR’ allows wheel travel, anti squat and shock rate to be balanced individually. It’s a development that dramatically improves performance and is instantly recognisable on the trail.
"The resultant efficiency enables the bike to climb with prowess"
“Each design element was selected to work in unison.”
“The Rear Kinematics were designed to give a progressive shock rate, keeping the bike supple to find grip early in the stroke before ramping up to provide mid travel support and bottom out resistance.”
The design philosophy led to the high pivot and idler layout adopted for the Saker. With the pivot positioned higher in the frame the arc of the rear axle path extends rearwards through the majority of its travel. This location allows the bike to carry speed over the rough stuff without significant weight transfer shifts during compressions and through corners.
With high pivot points and anti squat geometries the chain line can interfere with the suspension action is an unwanted feature among many bikes. A rearward axle path, whether it is achieved via single pivot or virtual pivots, will have increased chain extension unless the chain line is altered. The idler reroutes the chain to minimise feedback and acts as a chain retention for added security.
The idler redirects the chain line so force vectors combine to give close to 100% anti squat characteristics in the lower gears. The resultant efficiency enables the bike to climb with prowess and is yet another benefit of the idler design.
The shock is activated by a rocker positioned low in the frame, driven by a droplink from the swing arm. With the versatility of this layout a progressive motion ratio can defined, keeping the bike supple and allowing it to find grip at the start of the shock stroke while maintaining support during heavy impacts. Controlling progression of the shock via the kinematics keeps the spring rate and damping level ratios consistent ensuring dynamic control and composure on the trail. There is no need to compensate for poor development and compromise shock settings, volume reducing spacers which harm thermal management are not required.
