I think rather than Dura Ace, he meant to say KiloTT.

What are you talking about - street racing? You've got 300k miles on a track... Get a bike and ride it fast in street races. Did I mention - what are street races?

You have a ton of track experience, you can ride 53x14 uphill and you are asking us what bike you should ride? Did you hit your head?

The answer I want to give is to take one of those track bikes you test rode and slacken the head angle. Maybe lengthen the chain stays. But you know that.
