7.2.4. CdA Mode
The resistance in this mode can
be likened to air drag, and applies
resistance proportional to speed. This
mode has settings from 0.00 (“off”) to
0.20 (“very hard”). Out on the road the
faster you go the more resistance is
applied. When you slow down, eg. for a
climb, the resistance will back itself off.
This mode is great for applying
additional resistance without sacrificing
ride feel. This mode works well
when riding with a partner and the
performance difference is known. This
will let power requirements update over
undulating terrain (Manual Wattage
Mode will still apply up to 100w even on
steep hills).
(Session example, see page

)
7.2.5. Watts per km/h Mode.
Using this mode you’re able to add
0 to 2 watts of resistance (in 0.1 watt
increments) for every km/h of speed.
This mode is best used for general
riding as it simulates a constant, slight
incline on every road you ride on. The
incline steepens the closer you are to 2
watts per km/h.
For example, if you’re riding at 25km/h
and you’ve chosen 2 watts per km/h of
resistance, your total resistance applied
at that speed will be 50 watts. If you only
chose 1 watt per km/h for this speed
the AIRhub would apply 25 watts of
resistance.
