I've got a set of Bontrager Mustang rims that I want to build with some DT340 disc hubs that I got at a really good price. One of the rims is drilled normally (not OSB) and the other is Offset Spoke Bed (Asym).

These are rims that were intended for V-brakes and so the OSB rim was intended to be the rear rim. I'm thinking though that due to building these with disc hubs that it might be better to use the OSB rim up front and the normal rim in the back due to the changes in dimensions caused by the disc hubs. Does this sound like a good idea?

I've seen plenty of spoke calculators online, but none of them seem to allow for the change due to asym rim. How do I calculate my spoke lengths for the wheel with the asym rim?

Thanks!

I would use the OSB in the rear. I think you could be safe using normal spoke lenghts and would have enough adjustment for dish to center the rim. OSB are what 3-4mm off set? You could just guess-ta-mate maybe 1mm longer DS and 1mm shorter for NDS
