Hi,

i think the main misunderstanding is because i stated that there is a bb lockring on my 7sp freewheel. since i have never taken apart a freewheel before i do not know the assembly of it. i think the point all of you have been trying to make to me is that a freewheel does not use a lockring to keep it on the hub, correct? that a freewheel is simply a cluster that threads onto the hub and threads off by using a freewheel remover tool (in my case i will use a bb tool because the grooves and notches line up).

if that's the case, then what i mean to say is that my bb tool fits into my freewheel and i can remove the freewheel by using the bb tool. sorry for the terminology mixup there.

i actually just finished my freehub ss project a few days ago using a 7sp freehub, spacers, and an 18t cog, and everything is held by a lockring. so i am not confusing freehub and freewheel.

so my goal now is to make a ss project out of a freewheel, so i will either use a bmx freewheel or a singlespeed freewheel (are they just different terms for the same thing???). and i take it that a freewheel cluster has the backpedaling mech, while a singlespeed freewheel or bmx freewheel does not allow for backpedaling? since this is the case, pedaling backwards will cause the freewheel to unthread correct? what are some methods preventing this from happening? also, is it possible to space the singlespeed freewheel towards the outside (like how i used spacers on the cassette body to space my cog to the outside)? is this done by dishing the wheel?
