I think it will just be a freecoaster!!
Pedal forward!!
Pedal backward or roll backward and the pedals will stay where they are!!
All your doing is removing the brake. The brake wont be able to engage, thats about it!!
Pedal backwards all ya like, it shouldn't do nowt!!
Or you could use an ACS Freecoaster which only works on Alloy hubbed tuffs!!
And then you can do both. Freecoaster or twiddle with 2 dials and then have ya coaster brake back working again. The ACS freecoster is heavy though!!
