A five speed freewheel has way more room than on nlerner’s hub with about 5mm to the face of the small sprocket. Two compact 6s have 3.5-4mm to the sprocket. [snip]
Just a few data points for anyone interested.
Yep 32 mm is just right for Ultra-6 if the frame has proper clearance. On lots of vintage frames, 32 isn't enough even for a 5-sp though, so Phil is a risky choice unless you know your frame can handle it. Or you're willing to modify the frame of course.
Thanks for the data point. It looks like Phil probably offered more than one size in right-side axle caps for 120-121 mm hubs. Possibly the spec changed over time.
