Hello,
I have a 1978 Raleigh Super Course that I've recently installed a "new" drivetrain on. The
drivetrain now includes a 1950 model Sturmey Archer alloy AM hub (medium ratio 3 speed). The Super
Course frame was originally spaced to 126 mm in the rear. When I built up the wheel with the AM hub
I spaced the axle to 120 mm and had my LBS respace the frame to 120 as well. I didn't realize it at
the time, but this resulted in only being able to engage about 4 threads of each end of the axle
with the axle nuts. So, after a few test rides, I respaced the AW hub to about 114 mm to get better
thread engagement when mounted in the dropouts.
My question is, how important is it to now respace the frame dropouts to the same 114 mm as the AW
hub? I can mount the wheel easily, tightening the axle nuts simply squeezes the dropouts together.
But, am I risking damage to my frame or anything else by doing this?
Thanks in advance for any advice.
