This is the R-Series from Bristol firm Arrox Cycles; it’s an all-new aero road bike from some very interesting people and, thanks to a direct-sale model, its priced competitively amongst the high-end road bike market with complete builds starting at £2,199.
Arrox Cycles was founded when several Bristol-based aerospace engineers and automotive designers began to work together towards a common goal - to create the most efficient road bike out there.

The Arrox R-Series frame incorporates several unique features that the company is keen to make a noise about; most are aerodynamic details while others are used to optimise stiffness/strength values or improve the frame’s practicality.

Shoulder blades, top fins, tendons and more
Let’s talk a little more about the aerodynamic highlights of the carbon frame and fork of the R-Series. The fork itself gets what Arrox calls a ‘shoulder blade’, which is basically a large aerofoil section that integrates neatly into a sculpted section of the frame’s downtube.
To maximise stiffness, the top tube of the frame also carries a distinctive profile that Arrox refers to as its ‘top fin’. A large, integrated aero seat post is secured in the frame using a single titanium bolt. Beneath the seat post there’s a special guard built into the frame, this prevents its integral clamp from getting jammed inside the tube.
