I don't really see what is wrong with my post please enlighten me it appears no one has mentioned the difference in spacing when a derrailer and a multispeed fw are involved I simply stated that the old school mongoose 5 speeds were set up for that you could easily fit a sa 3spd, 5spd or even a nexus in it sram what ever but a multispeed fw or freehub wouldn't work you would probably crack the brake bridge and chainstay stiffener trying to stretch it
