​We showed you the prototype a couple of months ago, and now the time has come to pull back the curtains on the final product: the Arbr Saker in all its glory. Based around a high pivot design similar to that of the Commencal Supreme DH V4, this 160mm travel, futuristic looking carbon bike is designed and manufactured in the UK. The people behind the brand have extensive experience in designing suspension and other parts for Formula One and Moto GP racing, which they have combined with their passion for mountain bikes to develop what they label "the ultimate bike in its class". We could only afford the Saker such a prestigious title after very extensive testing, but suffice it to say that by the numbers, Arbr have certainly created a bike that should be fit for purpose. The geometry is resolutely modern, and our previous experience with high pivot points left us curious to see the concept applied to a contemporary enduro bike.

Needless to say, with a price tag of £4,390 (~$5550 USD) for just the frame and shock, the Saker is not headed for a big production run. Quite the opposite, as the bikes will be built to order. You do get to choose your color and each frame is laid up from start to finish by the same person, adding to that exclusive, personal touch of luxury you'd expect at this level of expenditure. Arbr even offers to repaint your frame if you tire of its appearance down the line, and they also offer "rolling upgrades" on parts if you buy a complete build.

UK company Arbr Limited today officially launches and presents its first product, the Arbr Saker.

Designed and developed over the last three years with a focus to define and integrate critical features to maximise descending performance while maintaining pedal efficiency for sprints and ascents. A high performance benchmark to exceed customer expectations and push forward the boundaries of what is achievable with a 160mm bike.

Manufactured from carbon fibre and aerospace core materials the Saker will be handcrafted in the UK with individual frames laminated by the same operator from start to finish. The entire process has been developed in house, engineered for performance by a team with over 25 years of combined experience in Formula 1. The result is a unique bicycle which will be made to order in limited volumes.

7075 T6 components, Titanium shafts for pivots and shock mounting, Boost 148 rear axle.

Arbr was founded in 2013 by Robert Barr who is an Engineer and Designer with a background that covers over 10 years of suspension design in Formula 1 as well as projects for MotoGP and World Superbikes. A combination of broad professional experience and a passion for cycling has given Rob the inspiration and knowledge to create such unique bicycle, transforming his initial concept into reality. To realize the vision a collaborative team was assembled, fusing expertise from friends and industry leading contacts. Each of them drawn to the project through a life-long passion for cycling along with the opportunity to develop and launch a next generation product from scratch. The journey has been a chance to think differently and collaborate with a diverse group that collectively hold similar ideals and vision.

We have taken our time going to market. That is what it takes when you are as obsessive about details as we are. Our vision is clearly defined – Producing the ultimate bike in its class. No compromises.

The design started with no constraints and a desire to achieve the following attributes:

  • 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.
  • Progressive rear shock rate, to maximise grip and maintain composure through big hits.
  • Stable geometry and balanced weight distribution.
  • Optimised lateral and torsional chassis stiffness

The Saker suspension design is defined by the term ‘HIPR’ which refers to combination of design elements working in unison: High single pivot, idler, progressive rate rocker mechanism. It’s a development that dramatically improves performance and is instantly recognizable on the trail.

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 against large impacts.

Handcrafted in the UK, each frame is laminated by the same operator.

Metallic interfaces for all bearings, high tolerance inserts for press fit BB92. Enduro bearings used throughout.

Each frame, logo and highlight are painted by hand, maintaining the personal hand-crafted approach to the way our bikes are made. Applying paint in this way is a painstaking process that delivers a stunning finish. The talents of those in the paint booths also adds flexibility for custom schemes befitting a bike of this level of craftsmanship.

GEOMETRY AND SPECIFICATION

Combined with the Saker’s suspension characteristics and construction our aim was to produce a responsive bike with huge stability. The final geometry is race inspired and modern with a long front centre, sensibly low bottom bracket and a slack head angle. It has been set to cope with high speed technical descents on steep terrain while providing an efficient seated position for climbing.

Chainstay and front centre lengths have been set to achieve a series of weight distribution targets. Across a variety of terrain and gradients this creates a bike in which the rider feels centred and balanced, with no extreme shifts of body position needed to achieve traction and grip through the tyres.

Each design feature has been combined and developed to work in harmony. The Saker delivers on descents and can be ridden all day. It delivers performance you can feel.

Frame highlights:

  • Wheel size: 27.5”
  • Shock: 215mm x 64mm
  • Rear Axle: 148mm
  • Rear travel: 160mm
  • Single ring specific.
  • Integrated chain guide.
