[Closed] what frame to replace a cervelo r2

So i have  r2 in a 54cm and rather enjoy riding it, a smashed mech hanger last week has resulted in some damage to the back of the frame and it is now not usable anymore. I had it built with dura ace and a new r8000 rear mech, to replace the frame with something equally nice but budget is £500. I also have a set of ultegra hydros disc brakes that were bound for the commuter but could be used on a new frame.

Looking for suggestions so far a discount on the Aithein disc frame puts it within budget but would build into a heavier bike overall.

any suggestions gratefully received
