The hottest competition these days is in direct sales and one of the latest companies to join the fray is Arrox, a Bristol-based brand founded by a group of aerospace engineers. The R1 is the brand’s first ever bike, and on test here we have the top-spec Arrox R1.3 Dura Ace version with its own-brand carbon clinchers.
What’s in a frame?
As the innumerable pretty graphics on Arrox’s website demonstrate, this is a brand that places some emphasis on its engineering chops and the R1 boasts, among other things, an “unbeatable stiffness-to-weight ratio”. Arrox supports this claim by referencing data from German publication Tour Magazin, although we should point out that Tour has not yet tested the Arrox, and we have no way of validating Arrox’s own testing protocol.

The virtues of the R1 frameset are broken down into what Arrox calls “eight unique genes”, purporting to offer all sorts of stiff, aero goodness. The upper end of the fork legs are referred to as ‘shoulder blades’ (for stiffness and aero), while the cut-out sections on the underside of the downtube near the fork are referred to as the ‘stream diffuser’ (for aero).
The top tube’s pointy ‘aero spine’ is designed to act as an airflow separator, helping maintain laminar flow as air moves towards the seatpost, and the confusingly-named ‘top fin’ tube profile aims to offer maximum stiffness.
