Add-on Aero Bars to an Already Aero Handlebar I've recently upgraded from a Specialized Allez to a (3T Strada Pro Force).  I took it on its first long ride (56 miles) and my, already bad, wrists really suffered.  I changed hand positions as often as I could, but it was still an uncomfortable ride.  On my Allez, I have a set of Profile Airstryke aero bars which have been great because being in an aero position takes the pressure off my wrists.

The 3T Strada Pro comes with Aeronova Aero Handlebars.  With them having a flatter shape, I'm not sure if there are any add-on aero bars, like the Airstrykes, that can attach to this handlebar.

Although I enjoy riding in the aero position, I do it more for comfort and hand position options than I do for aerodynamics.  Are there any add-on aero bars that I can purchase that will fit this type of handlebar?
Most clip-on aero bars attach near the stem, where the handle bars have a round profile, not where the bars have a flat profile. The elbow pads are outboard of the mounting point, which will put them over the flat portion of the bars.

As an aside I would try to assess why you are experiencing wrist issues.  You may simply need adjust your setup. It is also possible that on the new bars you are twisting wrists. Ideally you want to keep your wrists straight as possible. You may need to adjust the position of shifter/brake on the bars to help facilitate.
