I need to find out what length spokes i need to use with the hubs and rims i have. The site i got my hubs off doesnt give any measurements of the hub. I know theres online calculators but theyre really confusing and i dont know what parts to measure on the hubs haha.

Which parts of the hub do i need to measure and which calculator is simpleto use?

Theyre 700c 27mm deep halo rims and the hub is a planet x pista front and rear hubs by the way.

Cheers
