System Ex Flanged Hubs
04 Oct 2014
Hi, I'm building wheels based on Sun 27 x 1" alloy rims (ERD = 619). I have an old steel frame (1950's Armstrong Moth) which has 120 mm rear fork clearance and currently runs a 7 speed free whee (just!)l. Will System EX flanged hubs fit my configuration ? .. Your description says "will accept regular size single speed freewheel" .. to me this means they won't take a 7 speed free wheel ?
SJS Customer Service:

This is a single speed hub, designed to take either a fixed sprocket or a single speed freewheel so it will unfortunately not be able to take a 7spd freewheel.
