Using a rim with an offset spoke bed will make the wheel stronger.
According to White Industries's website
, the H2 has a center-to-left-flange dimension of 36.0mm (Shimano freehub) and a center-to-right-flange dimension of 18.0mm. Since the difference in spoke tension between left and right sides is dictated by the ratio of the left and right spoke bracing angles, the significant difference in left-right flange distances from center will overshadow any minor increase in right flange diameter. The offset spoke holes from a rim such as the Velocity Aerohead will offer more effect to equalizing left-right spoke tensions than a 14.5mm increase in right flange diameter.
Running the numbers for a Velocity Aerohead-sized rim with the H2 hub yields a left-right tension of 50% (i.e., left side tension is half of right side's) if the Aerohead has no offset. With a 4mm offset, the same rim/hub yields a left-right tension of 70%. A more even tension generally means a stronger and more durable wheel.
Interestingly enough, if we decrease the right flange diameter to match the left's, we get no change in tension difference at all. This means that either I did my math wrong (
), or the feature has no appreciable effect on wheel strength/durability.
FWIW, I have a set of Aerohead rimmed wheels. They're fine although I wish the machined braking surface was a bit taller. In addition, as previous threads on this forum has shown, Velocity is a very service-oriented company that is well worth supporting.
