Does anybody have a tech doc or a web link with data for a Shimano DH-3D72 dynamo hub? I'm coming up with zilch on the web.

Thanks!

So I called, and they don't have the numbers. They'll get back to me. Hopefully.

I think -- but I'm not positive -- that it's the same as the Alfine 501 model dynamo.

Oops, that was quick -- they called back and left a voice mail message with numbers as I was tapping out my reply on my phone.

Shimano DH-3D72 DH3D72 disc dynamo hub wheelbuilding dimensions:

Spoke circle diameter 70.0mm
Center to left flange 22.35mm
Center to right flange offset 29.95mm

There... Now the data will show up in a Google search for anybody else trying to do their spoke length calculations.
