Bike polo mechanics & fixing

This:

Tarty bikes recommend to give all the freewheels a bit of a degrease before trials use so they settle in properly as the factory grease is a bit heavy. I think I gt85'd mine thenadded a little light oil, it's been sweet.

Not this:

GT85 and WD40 would wash away heavier oils, i.e. lubriants, then evaporate, leaving your freewheel clicky, but also dry grindy and terminal.

Based on my understanding the grease might prevent the pawls to engage properly hence the Echo 108 comes with very little grease in it and even then you are requested to spray plenty of GT85.
