Greetings.

Does anyone know the sizing of the SH freehub body? Width, spline
depth and radius of the drum?

Regards.

Measuring an XTR 950 8/9spd Ti freehub body with a reasonable Vernier
caliper, I get:

a) Max. diameter over splines: 34.6mm

b) Min diameter to base of splines: 32.2mm

c) Width (from the shoulder that supports the largest sprocket to the outer
end of the freehub body): 34.8mm

The splines stop 1.6mm short of the outer end of the body.

The internal measurements corresponding to a) and b) from an XTR M900
cassette spider are 34.9mm and 32.5mm respectively.

Eight of the nine male splines of the freehub body are 6.0mm wide at their
base, and the ninth is 3.1mm

Allow a little margin for hand shake - say 10mm either way.
