As such, the head tube, down tube and chain stays are dramatically oversized while the T-shaped top tube and spindly seat stays are pared down for weight savings. The chain stays also bear unique pass-through ports that supposedly further improve rigidity by adding surface area.
Up front, the bladed fork is equipped with a long trailing crown to help ease airflow transition to the down tube and the deep-profile seat tube includes a close-fitting cutout for the rear wheel. Bianchi specifies the D2 with a 76 degree seat tube angle but an adjustable head for the integrated design will allow for substantial fore-aft movement to accommodate both time trial and triathlon applications.
Claimed frame weight is 1350g; the matching fork is said to be 450g.
