After a conversation with Michael at Easton about the continued issue with the interface with the AeroForce aerobars and the DeltaForce base bars, I concluded that I needed to come up with some type of material that is double sided and has a decent amount of friction that would be placed between the aerobars and the top of the base bars. It was mentioned to me by Michael that the biggest issue is where the two carbon components mate (yes, I do know that there's a clearcoat...). I believe that this is the biggest reason why the bars are slipping. After testing a couple of different materials, I came up with a solution.
This final photo shows the right side extension installed with the mesh in place (look below the white torque spec decal). If you look on the other side of the stem, you can see the surface of the base bars where the other extension was installed.
With all of this said, I'm glad to have this taken care of. I want to thank Michael at Easton for his concern and his willingness to help. I hope that Easton addresses that lack of technical knowledge that I experienced with Veltec Sports. A top notch product needs top notch support.
