well.... dosn't a freewheel cog have more threads than a track cog? im just imagining the freewheel would only screw half way or 3/4s way onto the track hub...

i dunno, i just wanna make sure my buddy is safe and a bike shop isn't just telling him "oh yah its cool" when it isn't lol

im stilll sort of bike-newbish, but hes even more newb than me and asks me for info so im trying to make sure things are cool and he isn't being duped.
