This Orbea Orca Aero 2013 road bike is a high-performance machine designed for speed and agility. With a lightweight carbon fiber frame, hydraulic rim brakes, and 22 speed shifter, this bike is perfect for serious cyclists looking to take their riding to the next level. The 700C wheel size and tubeless tires provide a smooth ride, while the 55cm frame size ensures a comfortable fit for riders of most heights. Whether you're racing or putting in miles on the open road, this bike is ready to take on any challenge.I was able to use tri-bars on the front and garmin varia radar on the post.
