I've only just set up a dual brake bike to start this one
Funny but i always thought it would be one of the easier tricks (i don't know why)
It has taking a fair bit to just get a full spin but on the weekend at the UK battle vibes i got a few brakeless (not landed but 1 -2 full spins) with ride in and it felt pretty good
I have been able to do to half lash ride in for a while but never tried the actual trick until i set up rear brake
