Duhhhh, Shimano hb-m752 or hb-m753 ???

[Marcel]

Lo,

I-m trying to discover the differences between Shimano front hubs hb-m752 and hb-m753. XT, that is.
One has a CrMo axle, the other an aluminium. A Japanese side -tells- me (if I interpret it
correctly), that they both weigh about 150 Gr. including the quickrelease. I suppose there must be
some -functional- difference? But what is it? (Yep, I already found the technical pdf-s, but they
don-t tell me much.)

Greetings from the Dutch Lowlands, Marcel.

Looks like from Shimano's site, the axle is the only difference.

Yep, right. Usually Shimano mentions weight. But, they don-t mention the weight of these on the
-readable- Shimano-site, on a Japanese site they do. I think. And there doesn-t seem to be much of a
difference. The CrMo seems to be 1 gram lighter. But perhaps I-m wrong. Perhaps the alloy one is
stiffer? Or....?
