andy, the bb is one of those pressfit 30 bb's. not my idea, sram's. the design seems to be gaining momentum. why not? it's a good one who's time seems to have come. hopefully some other big hitters in the bike part world will hop on the train.
Tell me more about that head tube. In the pictures it doesn't look tapered, is it tapered on the inside or is it oversized and your using a tapered headset?
Also, is it lugged? There seems to be something going on there.
david, the head tube is a constant 44mm inner diameter. both cane creek and chris king make headsets that allow a short stack upper cup that sits down in the tube, and a external cup on the bottom.
the "lug" you see is a gusset made with what is called bilaminate construction. basically, a sleeve that is brazed onto the down tube before mitered and brazed onto the head tube. extra work, yes, but worth it, i think.

So close to calling you to place an order.
