Spoke tension differential....(9 posts)

What is the spoke tension differential supposed to be on drive side vs. non-drive side of rear wheel in a wheel with conventional spoking (32)?

The differential is dependent on the dish. The greater the dish, the greater the difference. That is why there is no difference on the front, this does not apply to front disc brake wheels. Different hubs by variable manufacturers have different dish values.

I'm not sure how to answer your question but I do know that there is a noticable difference between the two. Non-drive side tension is quite low which allows a considerably thinner spoke to be used with no loss of durability. I use 14/15's on the drive side but 15/16's or Revolutions on non-dive side (brass nipples all around). When truing, bring up the tension slowly working from side to side keeping a close watch on dish. Keep tightening until the 14/15's are as tight as you dare. The non-drive side tension will be dictated by the drive side and the dish.

Good luck.

Thanks for the input. I wasn't as specific as I should have been. I am assuming that once proper dish is achieved the tension on the non-drive side will be dictated by the proper dish and proper tension on the drive side. In my case, this has amounted to about a 25% difference from the drive to non-drive side.

shows drive side as 102-114 Kg and non-drive as 61-73 Kg. Front are 90-102 Kg.

As others have noted, this depends on the hub used, the rim used, and the spokes used. You cannot categorically state that the tension is a particular number. The smart aleck answer to this question is that the differential is "enough to properly dish the wheel" and that the overall tension is "enough to build a strong wheel" since neither of these numbers can be stated a priori.
Whatever it takes to center the rim. (nm)Al1943

Amen. Thanks again for the input.
