It is a steel frame "Adventure Road", Chris King wheels, etc., Shimano hydraulic discs (which I really do need around here), Di2 (which I don't need, but was bundled with hydraulic brakes at the time, and the shifting is flawless). This is the most stable bike I have ever ridden, and the best ride I have ever experienced with my clothes on.

I wanted to buy locally (Santa Cruz CA), and I really lucked out with John Caletti. Everything exceeded my expectations. My only regret is I waited until I was 50 years old and broke my ankle before I got this for myself as a recovery incentive/present.

I am pretty sure all the frame tubes are standard diameter. The frame is actually quite plush -- much more so than my SLX Bianchi from 1987.

The rack is a $40 Axiom DLX Streamliner Disc Cycle Rack. I got it on Amazon. I originally got it because it had a single central strut to connect to a single braze-on bold on the seat stay bridge. The bolt sheared off, but fortunately it also came with those horizontal struts you saw, and I've attached those to a Salsa clamp.

John Caletti an extremely nice guy, and the diametric opposite of a pushy salesman. If anything, I had to talk him into a more expensive component set. Frankly, I'm not worthy of this bike -- too old, too slow, too fat, too lame from the ankle break, and a cheapskate who typically buys Nashbar instead of name brand -- when I showed up at his shop the first time about 4.5 years ago or so, I was still having trouble getting up and down from his doorstep. He had every reason to tell me to go away (which a few LBS essentially did), but he took me very seriously as a customer and built a bike with a better understanding of what I needed than I had, and it certainly wasn't for a lack of customers. There was about an 8 or 9 month wait, but for me it was worth it, and it gave me a goal to work toward in terms of recovery and hopefully got me into a bit better shape overall. I would definitely recommend him and the bikes he makes to anyone.
