    New question here. Spoke length

    I posted this on the "wheel" forum, but it doesn't seem to be getting much attention, maybe one of my SS brothers could help me out.
    Can someone double check my numbers. Here's the combo: Deore hubs, I think they are M-510 model number. Alex 24" vp-20 rims 36 hole. DT champion spokes. I would like to see what the lengths for radial, 2 cross and 3 cross would be. I am building a wheelset for my daughters new 24" mnt. bike. Thanks to all that reply

    here's what I calculated....

    Couldn't find exact numbers for those hubs, but I think most Shimano non-disc hubs are about the same dimensions. Here are the numbers Spocalc gave me...

    Thanks

    Thanks for the info. Where did you get that ERD? I couldn't find the right ERD so I used 507. That makes a huge difference.
    Anyone else have a different set of numbers?

    That is the ERD in the spocalc database for the Araya VP-20. I just assumed it was the same rim. There is a note with that entry to measure to be sure, though. 507mm is the tire bead diameter, so it should be smaller than that.

    Good job!

    Right you are, what was I thinking? I think the alex rim is an exact copy of the old araya design. I will measure the rims when I get a chance, to check. Thanks again.

    shimano measurements

    the shimano website lists the lengths for the flangs to center as:
    right to center: 23.2
    left to center: 18.55
    they are different than others i guess

    Thanks for the info. I did not know that shimano's web site had those specs.
    I think I have all the specs now. Here what I came up with now.
