I am seeing variation between inner and outer spoke tensions on straight pull wheels (3x but no interlacing). The guidance given to me is to have even tension of all spokes on each side of the wheel, and while I can achieve this it seems that a truly balanced wheel would have slightly higher tensions on the inner spokes compared to the outer spokes on the same flange.
My key question is how does this relate to the tangential force the spokes are exerting, as all the inner spokes on both sides are trailing while all the outer are leading. These forces must be equal as the trailing spokes are pulling against the leading spokes and hub will simply rotate to a point where the trailing and leading forces are equal.
It seems to me that the spokes must be providing equal rotational force despite different spoke tensions, because of their different distance from the centre of the hub.
So if I bring the inner and outer spokes on the drive side flange to the same tension I am thinking I must trying to laterally distort the rim, which doesn’t show up because the rims are so stiff? Or perhaps I am compensating with greater variance of tensions on the Non Drive Side of the wheel? I am going to set about measuring a straight pull wheel tensions to see the impact of evening up the tensions on the drive side, as my theory suggests it will be difficult to have even tensions for trailing and leading spokes on each flange. (Drive side flange obviously will be higher than NDS)
