Subject: Shimano free hub axle identification needed
|
How can I tell if a Shimano free hub will take an eight
speed cassette? I did not pay attention when I bought
it. It has no obvious identification marks. I run a
seven speed cassette. The view of the hub shell out
board of the NDS flange transverse to the axle has a
straight line silhouette.

Yes, but also, there are some bodies that accept
both Hyperglide and Uniglide cassettes, and some
of these are also 8-speed. Or at least, the 600
series FH-6402 mentioned by another poster is
(I have one right here).
The threads went away around the time they started
stepping down the splines to accomodate 11 tooth
cogs.

Measure the freehub body from the flange that the
cassette stops against to the end. A 7 speed freehub
will be about 31mm and an 8/9 speed hub about 35mm.
A 7 speed cassette is about (6*5+2) = 32mm wide
and an 8 speed cassette about (7*4.8+2) = 35.6mm wide.

Maybe, maybe not. That isn't definitive.
Older external (UG) bodies can be 5, 6, 7, or first-year DA8. Current
seven HG bodies have no outside threads.

Not all do - Alivio and STX are two examples without.
And some 8-speed bodies have external threads - Ultegra 6402 is an example.
