I've seen a couple of these, now I guess my next time around will be riding one.
One particular concern I have with this frame is the lack of waterbottle bosses on the DT and ST. The bikes I've seen are outfitted with twin cages hanging off the back of the seatpost, Tri-style.
I don't know if this is a limitation or a preference. I suspect drilling a hole for the bosses might encourage a crack to develop and the alternative would be to apply a CF wrap around the bamboo afixing each boss in position. I think too the four bands of CF might breakup the visual coolness of these pipes.
