The "AeroCleat" is the most advanced version of the standard Clamcleat Racing, because it has a special bottom part that allows you to move the cleat up or down along the depower rope. So you can adjust the height of the depower throw, according to your needs.
If you want to ride the waves, you can move the AeroCleat up, so you can have more depower throw while surfing the waves and "kill" the power of the kite instantly.
If you are tall, you will appreciate to move the Aerocleat higher.
If you are freestyling, you might want to move the cleat further down, so that the kite keeps a little bit of power.
Kids will appreciate to move the cleat down, so that they can access the trim more easily.
Note: the universal bars are preset with about 60 cm of depower throw, which most riders appreciate, especially in the waves or gusty winds. So you don't really need to change move the Aerocleat, but you can do it if you want.
