Wind tunnel results

Proven gains

Road-tested first, then independently tunnel tested — not modelled on a spreadsheet. Every figure below is measured hoods to drops on the same rider, same bike, same day.

Drops33 cm

The move being measured: hands in from 42 cm to 33 cm, tops to drops.

Seconds saved over a 40 km time trial

The stronger you are,
the more time you keep

Savings hood to drops, N'AERO 3DD™ model 42/33, 5 mph wind and 0–10° yaw. At 200 W the bar returns just over three minutes across 40 km.

How to read these numbers

Same rider. Same bike.
One position change.

Every result is the difference between riding the hoods and riding our drops — nothing else on the bike changed. That is why we call it free speed: you already own the equipment, you simply gain a position that was not available before.
