Used this hub to build a rear wheel for an old Raleigh Twenty folder. Had to spread the rear triangles a bit to accomodate the 135 mm OLD. Took a little time to get reaquanited with the coaster brake feature. Very happy with the hub. Decent gear range, reliable shifting and a much better rear brake than was originally on the bike! The original intent was to not have any other brake on this bike (used as a commuter). Have kept the front brake to deal with longer downhills where coaster brake could overheat. Great value for a great commuter hub
