Shimano freewheels
How do I tell how many speed cassette the freewheel takes on the wheels I've been given?
My worse day on my bike is better than my best day at work!
Re: Shimano freewheels
7 speed freewheels are about 35mm long.
8/9 are about 39mm.

To clarify;
7s = 6 x (4.9mm) + 1.9 = ~31.3mm
8s = 7 x (4.8mm) + 1.9 = ~35.5mm
9s = 8 x (4,35mm) + 1.9 = ~ 36.7mm
in each case the dimension is from the inside of the #1 sprocket to the outside of the smallest sprocket.
Blackbike's dimensions are about right for the length from the shoulder (on the freehub body or the freewheel thread) to the inside face of the dropout, i.e. they are greater than the width of the freewheel/cassette by about half the width of the chain, so that the chain doesn't foul the dropout when you are using the smallest sprocket.

Re: Shimano freewheels
Where do I measure on an empty freewheel?
Mine measures 35mm from the lip at the wheel end to outer edge.
Presume it's 8 spd.

Re: Shimano freewheels
which do you have?
If a cassette with ~35mm long splines, you have 8s/9s/10s.
