Data Fields

On the Hammerhead Karoo the myWindsock extension provides these additional data fields.

Please note: A data connection is required before you begin your ride to retreive the current weather. Although not required, keeping your Karoo connected will ensure your data is kept current for your location. There is no need to upload a route for myWindsock data to work.

Wind Field

Wind Field Pictured in User’s Selected units of KPH.

Displays the current Average Wind Speed, Max Gust in your selected speed unit. The field alters colour depending on the relative wind bearing. Red indicates Headwind and Blue is tailwind. The direction arrow indicates the angle of the wind relative to your direction of travel.

Forces

This is the distribution of forces:

  • Dark Green – Rolling Resistance
  • Light Green – Gravity
  • Blue – Air Resistance

How to use

When the ‘green forces’ of Rolling and Gravity are greater than 50% of the field area, this indicates to prioritise power production over aerodynamics. However, when the field is blue, aerodynamics should be your priority.

On an incline as your speed increases air resistance will increase more than the ‘green forces’. Keep an eye on this field to ensure you are being efficient as your speed increases.

Improving your data with a Power Meter

We want you to have the most precised data possible. For the Forces Data Field to be as accurate as possible we recommend using a power meter. This will allow us to calculate your aerodynamic efficiency in real-time.

Heawind Totals

This field keeps track of your time in headwinds. It will only begin counting when your ride is active.

  • Current Headwind – Time spent in the current headwind. This will reset when in a tailwind for longer than 1/6th of the current headwind duration.
  • Total Headwind – Accumulated time in headwinds during the active ride.

Feels Like Gradient

Showing wind is making the road field like a 0.9% gradient even though the true gradient is 0.

The Feels Like Grade is the current road feel when the wind resistance and gradient are combined.

Air Speed

The estimated air speed when ground speed and prevailing wind are combined. This takes into account wind shear/gradient when the roughness of the terrain slows the wind from forecast.
