Thanks, it is, sort of. The seller's dad was a pro racer, who checked out the manufacturing process thoroughly (China), and then ordered it from Airborne. He specified the DT shifter braze-ons, plus the cable guides below the top tube, along with the size and geometry. I bought it from his son before it had ever been built. It took a while to "like," but once I built the wheels and got the fit right, you'd have to pry it loose....

Since then I've bought a couple more frames from him. If he called me today and said he had another one, I'd probably take it sight unseen.

The only downside to it, so far, is that it puts some of my other bikes into a different "prospective." They seem more expendable.
