Knock AerSpeed

The stripped back, speedier brother to the AerGrind, the AerSpeed also features 38mm burrs, but with a 5 vain burr that allows for up to 25% speed increases in grinding at a given point.

This minor change in Aerspeed burr profile narrows the adjustment range for espresso, but opens up a wider range of adjustment from Aeropress through to French press.
