Spoke length calculation

Looking to rebuild my wheels with revolutions, done a few builds before all went well. Does anyone know of a good calculator, I am sure DT swiss had a list of hub models, but now you need to enter measurements, I could but I am lazy. Or has anyone else built a front and rear with Mavic 717 and Hope XC hubs, seems a pretty common set-up. Plus where do you buy, CRC seems the best but they come with Brass nipples, I know know Alloy are not as good, but thought I would see how they go. Other shops seem to charge a lot of cash well over a £1 a spoke so getting on to £70 for both wheels, it is supposed to be a cheap upgrade. Cheers for the info in advance.

DT only list their own rims and hubs now. Barstards ;-).

Once you have unbuilt your wheels, you can simply measure the spokes.

ERD of the rim is simple enough at 538.5mm. Hope should list the other bits.

This morning measuring up, I came to the same conclusion as your advice just measure the existing spokes. Cheers
