There are more aero developments. The integrated handlebar sits
flush in the stepped head tube, with aero shaped collars providing
stack adjustment without impairing aerodynamics. A new aero
seatpost is reversible providing two setback options for greater
fit potential. Cable routing has been revised with an eye on
compatibility with all currently available groupsets and reducing
drag. A port on the top tube can be adapted for mechanical,
electronic and wireless.
The new Orca Aero makes use of the direct mount brake standard,
which provides better aerodynamics, partly by allowing the fork
crown height to be reduced, and also ups tyre clearance to 28mm, so
you can have some comfort with your aero gains. Comfort isn't a
word mentioned in the Orbea product release, but stiffness
certainly is. The head tube, downtube, bottom bracket and
chainstays have been developed to create a "stiff spine" that
provides optimal power transfer.
