For time triallists serious about aero optimisation, the Notio is a good investment - but to get the most out of it you need time as well as money

Cycling Weekly Verdict

The Notio is a really fun bit of kit, crucial for any self-confessed aero-nerd. If you're looking to crack 20 for a 10-mile TT, or just looking to get as fast as possible, you need a Notio. It genuinely is like a pocket sized wind tunnel and Notio’s associated apps and data analysis is fantastic too. However, at a price of $600 or higher depending on territory, it's probably not worth it for the average rider.

The Notio Aerometer is a device you attach to the front of your bicycle and it measures how aerodynamic you are. These kinds of devices are relatively new to the market, only coming about in the last couple of years and have opened up aerodynamic testing to more people. 

Getting your hands on this type of data in the past would’ve required a costly and time consuming trip to the wind tunnel. That is essentially what the Notio aims to do - strap a miniature wind tunnel to the front of your bicycle.
