Coolio's

Last minute wheelbuilding, just wanted to check my spoke lengths before I buy them and start lacing.

rims: Mavic Ma40 rims (36 hole, ERD 613mm) hubs: Mavic 500 RD 100/126mm. 3 cross, planning to use DT db spokes.

I get 297.0 front and 297.0/295.3 (left/right) rear.

I have seen some reference to the Mavic ERD >> ERD is Mavic's Nipple Seat Dia + 3mm for nipples << ... Not sure what that means and whether I should go longer to accommodate? Given I'll be buying spokes in even number lengths what's best to go for? Both the hubs and rims have been built before but the hubs have only moderate gouging and the rims are otherwise like new.

Thanks in advance !!!
