Hub Dimensions For Old DX Hubs (HB-MT60 & FH-MT62)

[Varanasi Benares]

Is there anyone who would be kind enough to look up the dimensions of
these hubs for me. I would like to build some wheels using a set of old
Deore hubs, but I cannot find the specs I need to calculate the proper
spoke lengths.

The Shimano part numbers are HB-MT60 and FH-MT62. They were introduced
in the late 1990s, I believe. I can't find any reference to them on the
Shimano website (or to their dimensions anywhere else.)

The dimensions I need to use the spoke length calculator are:

Spoke hole diameter (probably 2.4mm?)

Diameter of the circle through the centers of the spoke holes for right
and left flanges

Hub width from the center of the wheel to the center of the right and
left flanges

I know that I could measure these things myself, but I don't trust
myself to do it precisely enough.

Thanks.

Most Shimano hubs of this era had very similar hub shell dimensions. The
DX, LX and XT series were identical.

From Spocalc (626, 627 - XTII, DX):

Spocalc says 2.6mm

Front: 38mm
Rear: 45mm

> Hub width from the center of the wheel to the center of the

Rear: left: 35.6 right: 25.0
Front: 35.8

Great precision isn't necessary - a cheap caliper is perfectly adequate.
The effective rim diameter is by far the most important variable.
