Are you looking to buy some spokes? I got some from the cycle clinic who advertise on here at a cracking price he will supply the correct length.

If you look at this site:

And read the Spoke length tutorial

Measure the rim, i´ll help you find the spoke length.

I did a wheel building thread a while back I called it that in which I desribed how to measure the hubs and ERD and provided a link the excel file of spoc calc. I have no idea of the dimensions of the hubs and rims you have. They will have to be measured. All you need to do this is two spokes cut down to 200mm and nipples treaded. Add to that the most useful tool anyone can have a vernier gauge and you can measure everything up. I could calculate the spoke lengths from those dimension. Either that or you will have to get someone to measure up for you.

Front 36 hole 3 cross = 299mm
Rear 36 Hole 3 cross = 299mm non drive side
Rear 36 Hole 3 cross = 297mm drive side

There's sound advice here Effective Rim Diameter (ERD)

Take note especially of the bit that says "Average several diameters."
