Hub: Novatec F482SB, with ABG freehub, 32H 4xDS 2xNDS ... this lacing should give almost equal DS/NDS spoke tension
I've seen this mentioned in this thread before, and it is absolutely not true.
Even if you could lace a 32h hub 4x, the nds tension would still be only 50%.
Hi Mackers, I checked a wheel that's laced 32H 4xDS 2xNDS, and the DS deflection tension was 62 and NDS was 57. DS was very tight. Not sure what hub was used but it was nothing special, and the rim was an eyeleted 20-22mm deep Alex rim (shallow rim). 14g SS spokes were used. I believe it was a 9 or 10 spd hub
I am not sure what 62 equates to in kgf but it would be well over 100, probably more like 120 to 130 or higher.
Lets say DS spokes were 120kgf then the NDS spokes would be approx 110kgf ... that is quite even/close, about 90% DS
Looking at the 4x lacing, the spokes pass initially over the spoke heads ( first cross), so I agree 4x on a 28H would depend on the flange dia and probably not a good idea, but possible. It would appear that a 4x lacing would be better done on a 36H hub, but can easily be done on a 32H hub and even a 28H hub (depending on hub and rim).
4x on a 28 hole wheel would seem to be too extreme. The optimal orientation is for the spoke to be exiting the flange perpendicular to an imaginary line crossing the center of the hub and the center of the specific spoke hole used.
