Thanks! Yeah, I was stoked to find a horizontal top tube, rigid mountain bike at all, let alone in a large size. So much so that I decided I could live with straight-gauge 4130 and probably paid a bit too much.

It is tempting to put some kind of shallow drop bars on it, but it's my only flat bar bike, so I think I'll try it that way for a while.

As for larger off-road/touring triples: There are a few out there. Velo-Orange's new triple crank comes in 28-36-48, and you can get a Sugino 26-36-46 crank from any QBP dealer. If you don't mind the more modern look, current-generation Shimano Deore cranksets come in a 26-36-48 model as well as the more common 22-32-44.
