    DH-3N80 36H dynohub dimensions?

    I want to order the shimano DH-3N80 36H dynohub and get the spokes at the same time, but can't find the dimensions anywhere (google, shimano.com, various forums) to plug into the spoke calculators. Does anyone have the necessary measurements?

    I used the EDD spoke calculators dimensions for the DH-3N72 dynamo hub to calculate needed spoke lengths for the 3N80 dynamo wheel I built and it worked great.

    Unfortunately so far as I can find Shimano documents dimensions for all of their hubs EXCEPT the dynamo ones in two documents on their web site. One covers IGH hubs and the other covers front and cassette hubs except for the Dynamo hubs.
