Freewheel query

[Mike Muz]

Hi folks,

Got some hubs for my Jackson project, very kindly donated by a member on here.
The space between the end of the thread and the frame dropout, is 36mm.
The question I have is, what width are 6 and 7 speed freewheels?

Thanks

Mike

I have a Sachs Maillard 6-speed, which is 31.7mm width, whereas the width of a Sachs Maillard 7-speed that I have is 36.5mm across. I have also used a mix of 6 and 7-speed sprockets and spacers on a 7-speed body to give a width of 30.6mm, which has been very handy to fit a 6-speed freewheel on Campag hubs in 120mm width rear dropouts.
