Title: Spoke lengths . . .
Post by: The VW Doc on April 19, 2011, 12:17 PM

Hi all - I have a bit of a problem and I hope you guys and girls can help me out.
I stripped a pair of original Weinmann rims, with Sturmy Archer hubs (from a Mk1 Raleigh Super Burner - The gold coloured one) down at the weekend with a view to refurbishing them.
Due to the ammount of corossion all the spokes either were or did bend very badly or snapped off (either at the nipple, or between 2-3" up from the nipple) leaving me with a load of uslelss spokes that I cant guarantee to get an accurate measure of to allow me to replace them.

Would anyone know for sure how long the spokes need to be so I can order up some replacements?

Pleas help!

Are they a large flange or small flange hub?

You may find this info on burnerworld, I think they have a tech data section.

For a 3 cross pattern with low flange hubs you need 194mm or if they are high flange (prob not) then you will need 183mm for a  3 cross pattern..

Cheers guys!
I am pretty sure the are small flange hubs

I have cropped out a photo of a (pre assembled) wheel and the hub so you can see

194mm sounds like what it is then :)

Cheers guys!
I guess the safest way will be to piece together the bits I have and see if I can get an idea of length
If that is inconclusive then to measure then up as dannywhac suggests
