Equal spoke length = equal tension?

Building up the rear wheel on Novatec disc hubs, A23 rims and my calcs (corroborated by Ugo) suggested equal spoke lengths on DS and NDS on rear.

Now of course "typically" you have a lower tension on the NDS with a longer spoke, should I expect equal tensions NDS and DS with the same length spokes? thanks.

    No, it's just because in that particular hub the left flange is bigger than the right, so it ends up being equal length... coincidence and irrelevant

    The forces exerted by the spokes on either side of the rim need to be equalised, but if the spoke angles vary, then the tensions will be different. For strong wheels, preference is to have as low a spoke angle as possible i.e. wider hub flange spacing. OP should have paid more attention in trigonometry class ;-)

    wider flange spacing mean high bracing angle not lower Monty. the bracing angle is the angle the spoke is at from the vertical that is how it is all defined.

    Aaaanyway it all worked out OK in the end. Lovely looking wheels. White hubs and black everything else, how very unoriginal ;-)
