Since launching our original Aero System last year in response gravel racing evolving to become moredefined by tactics, speed, efficiency and marginal gains, the scene continues to expand further alongwith the needs of the rider.
Adding a Bolt-On version of our Aero Top Tube Module was the next natural extension, followed by a Bolt-On Long version, to create a complete system designed to make you faster.
Of course to make any meaningful claims we needed to test the modules properly in the wind tunnel. Pro gravel racer Dylan Johnson found the Aero Bolt-On Top Tube Module saved 4.2 watts when used in isolation and 5.2 watts when used in combination with the Aero Frame Module.

The real test however would come at the world’s biggest gravel race - Unbound, where a number of riders had put their trust in the Aero Top Tube Modules to give them the competitive edge. The results speak for themselves:
