New system claimed to be able to measure CdA with +\/- 1.5 per cent repeatability on the road <\/p>

Aerosensor has launched its Aerodynamic Cycling System (ACS), a suite of products aimed at allowing individual riders to measure their aerodynamic drag<\/a> in real-time, on the road or on the track.<\/p>\n

The Aerosensor ACS consists of three devices: the Aerosensor, the Aerobody and the Aerodrome.<\/p>\n

The Aerosensor is a handlebar-mounted probe designed to measure wind speed and angle to +\/- 0.1 per cent accuracy.<\/p>\n

When this data is combined with power data\u00a0and tyre rolling resistance<\/a> data, the Aerosensor probe can calculate a rider\u2019s real-time coefficient of aerodynamic drag (CdA) and display it on a Garmin Edge bike computer<\/a> via the Aerosensor Garmin Connect IQ app.<\/p>\n

The Aerobody is a stem-mounted device which uses lasers to measure a rider\u2019s body position, to ensure a consistent position is held during testing or riding.<\/p>\n

Lastly, the Aerodrome is a wireless lap trigger designed to track lap times with \u201cmillisecond accuracy\u201d.<\/p>\n

Aerosensor says the Aerodynamic Cycling System can be used on the road to determine differences in CdA of \u201caround +\/-1.5 per cent\u201d, or on a velodrome track to +\/- 0.5 per cent.<\/p>\n

The Aerosensor itself is the heart of the Aerodynamic Cycling System.<\/p>\n

It measures wind speed, wind angle and altitude, then combines this with data from a speed sensor and a power meter<\/a> to calculate a live CdA.<\/p>\n

This figure is then transmitted to a Garmin Edge bike computer via ANT+ where it can be displayed in real-time or recorded to the ride\u2019s FIT file.<\/p>\n

Currently, the Aerosensor is only compatible with Garmin Edge bike computers. It can be mounted to a handlebar using a GoPro<\/a>-style mount.<\/p>\n

Developed by former Formula 1 aerodynamicist, Dr Barney Garrood, the Aerosensor uses a patented probe design which is said to provide robust data in wind angles of up to 50 degrees of yaw.<\/p>\n

This enables \u201cpeerless repeatability in practically all wind conditions\u201d, according to Aerosensor.<\/p>\n

The latter point is key, as other existing products on the market, such as the Noti Konect<\/a> or Velocomp Aeropod, typically require you to test on wind-free days for good results.<\/p>\n

According to Dr Garrood, tyre rolling resistance data can be gleaned from independent sources to enable the Aerosensor to account for this variable.<\/p>\n

When real-world rolling resistance cannot be precisely calculated, Dr Garrood says assuming a fixed figure within the right ballpark would not affect the repeatability of test results.<\/p>\n

The Aerosensor costs \u00a3850.<\/p>\n

Aerobody<\/h2>\n

The Aerobody is designed to help you maintain a consistent body position while riding or testing.<\/span><\/figcaption> Aerosensor \/ Alex Duffil via Drive Change Media<\/i><\/span><\/div>\n

When doing comparative tests of body positions or equipment, maintaining a consistent position on the bike is crucial for getting good results.<\/p>\n

This is because any differences due to changes in body position are likely to outweigh those found between two different pieces of equipment, such as wheelsets<\/a> or aero helmets<\/a>.<\/p>\n

Likewise, once you\u2019ve found an aerodynamic riding position, it\u2019s important to know whether this can actually be maintained while riding and when fatigued.<\/p>\n

In response to this, Aerosensor has developed the Aerobody.<\/p>\n

\"Aerosensor\n<\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/source><\/picture>\n<\/div>
The Aerobody integrates with the Aerosensor Garmin Connect IQ app to display and record body position data.<\/span><\/figcaption> Aerosensor \/ Alex Duffil via Drive Change Media<\/i><\/span><\/div>\n

The Aerobody mounts to your stem like a band-on bike computer mount and uses optical sensors to measure the position of your head, torso and abdomen.<\/p>\n

If your body position then deviates from the predetermined starting point while riding, the Aerobody will notify you via the Aerosensor Garmin Connect IQ app.<\/p>\n

According to Aerosensor, the Aerobody can detect changes in position of 1mm.<\/p>\n

Body position data is also recorded to the ride\u2019s FIT file so it can be compared to aero drag data post-ride.<\/p>\n

The Aerobody costs \u00a3365.<\/p>

Aerodrome<\/h2>\n

According to Aerosensor, having accurate lap data can \u201csignificantly improve\u201d the accuracy and repeatability of aerodynamic test data.<\/p>\n

The Aerodrome uses a tape switch \u2013 a pressure-sensitive switch that is ridden over to trigger a lap \u2013 with a claimed \u201csub-millisecond accuracy\u201d.<\/p>\n

This data is then transmitted wirelessly to the Aerosensor, which then transmits it to the Aerosensor Garmin Connect IQ app alongside the aero data, where it can offer lap-based CdA averages.<\/p>\n

The system is said to be easy to set up and use.<\/span><\/figcaption> Aerosensor \/ Alex Duffil via Drive Change Media<\/i><\/span><\/div>\n

According to Dr Garrood, one of the key advantages of the Aerosensor ACS is that it\u2019s relatively easy to use.<\/p>\n

It\u2019s claimed a rider can be up and running with the Aerosensor within 10 minutes of unboxing it.<\/p>\n

Dr Garrood says the device is able to automatically calibrate itself while you ride, meaning there isn\u2019t a need to perform a specific calibration protocol prior to testing, as with some competitor devices.<\/p>\n

The Aerosensor ACS can be purchased directly from Aerosensor, as individual components or as part of three system bundles.<\/p>\n
