Replace the drive side spokes with Sapim Race or DT Competitions. That will improve things.

A weak rim will bend under load when being loaded sideways which means that even though it will bend at the road surface it will not bend as much the other way at the brakepads. The deformation of a super stiff rim look more like a rotation around the center which means it will deflect more at the oposite site of the load.
If I set my brakepads just a little wider than normal I have no problems.
A hub with better geometries will be better to prevent the stiff rims to rotate around the hub. Rumors says ENVE are coming with their own hubset with optimized geomtry to their rims.

Sapim Race spokes are stiffer because there is more material. All high-end spokes are made from stainless steel. CX-Rays do not have some magic formula. The bladed portion is forged from a 1.5mm round section of spoke (the Sapim Laser). The Race spokes are 1.8mm along the same portion of the spoke. Race spokes have 43% more material along their length than CX-Rays. More material, more resistance to stretch. Less stretch, stiffer.
CX-Rays are purported to have a longer life span because of the blade forging process, but I haven't had issues with round spokes either. The rim is typically the wear item in a wheel built right due to braking. I choose CX-Rays for wheels where aerodynamics are a priority. If not, I use round, double-butted spokes. You won't find heavier gauge, bladed spokes that will work for the drive side of your wheel. Using Race spokes will improve the wheel for you and have an unmeasurable impact on the aerodynamics of your bike. Rim shape is far more important.

You have to have the spoke holes slotted and make sure the lengths are available. I use Sapim CX-Speed spokes for certain builds. They are 2.6 along the blade so they fit in some hubs. I've had to take a spiral scroll saw blade to other hubs. I do this by hand and remove a little material towards the center of the hub.
This set I do has the CX-Speed spokes on the drive side.
click for high rez.

I have to check those spokes out.
Thanks,

Adrien wrote:Nevertheless, because it is bladed, it will be laterally flexier than the DT Competition: the thickness of the spoke matters more than its width for the lateral stiffness, it is the dimensions that directly resists to lateral forces (second moment of area).
