With all due respect, why are you obsessing on getting these exact bars? They are simply dime-a-dozen aluminum ergo bars. I had a set come on my Specialized Tarmac. I threw them away because they are impossible to sell...even for $10.

Go to any bike shop and there will be a box of them in the corner taken off new bikes.

That flat part in the bend is actually undesirable because they offer only one position. Slightly curved bends feel better and are more popular for this reason. They feel better because you can move up and back a couple of CM and adjust the load angle on your wrists.
