During development, the focus was on the chassis. The aim was to largely eliminate critical points that impair responsiveness. According to company founder and developer Robert Barr, the result is a chassis that offers super downhill handling and the best possible pedaling efficiency on the climbs. Packaged in a handmade frame made of carbon fibers and core materials from the aerospace industry, Barr is convinced that he has pushed the boundaries of what is possible. With the "Saker", Arbr offers its customers a unique bike that is only available to order in limited numbers.

Development began without restrictions and with the aim of achieving the following attributes:
- A rearward-moving axle path for the best stroke processing and the ability to generate speed.
- 100 percent anti-rocking characteristic for pedal efficiency.
- Elimination of pedal kickback.
- Progressive spring characteristic for better grip and more reserves for rough impacts.
- Stable geometry and balanced weight distribution.
- Optimized lateral and torsional stiffness.

Each frame is also painted by hand and costs a "trifle" of £4,390, including the Fox "Float X" shock. So the Arbrs first "Saker" is definitely not a "quick number", but a "relationship" that should last a little longer.

Inspiration from racing

In addition to a sophisticated chassis and the unique look, the aim was to build a responsive bike that is also very stable. The final geometry is therefore race-inspired and modern with a long reach, low bottom bracket and slack steering angle. A steep seat angle was chosen to get the power to the ground on the climbs, but the chainstays were not made too short at 435 millimetres. This should distribute the weight better and keep the rider centered on the bike.
The frame designed for 27.5-inch wheels is available in two frame sizes: With a 437 millimeter reach for riders up to 178 centimeters and with 467 millimeters for bikers 175 centimeters and taller.

Experience gained in Hinwil

From the founding of the company in 2013 to the first sketch on the drawing board to production, everything happens under one roof. Above all, the fact that Arbr manufactures the frames by hand in the UK is not a matter of course. This is made possible by the combined 25 years of experience of the individual employees. Company founder, engineer and designer Robert Barr alone has over ten years of experience in Formula 1 suspension design, including at the Sauber racing team in Hinwil. His experience also includes projects in MotoGP and World Superbikes.

To realize the vision, a collaborative team was assembled, bringing together the expertise of friends and key industry contacts. With a lifelong passion for cycling and the opportunity to develop the next generation of mountain bikes, everyone at Arbr is motivated to drive the project forward.
