What's better than a lightweight, aerodynamic, fast road bike? A lightweight, aerodynamic, fast road bike with hydraulic disc brakes. Disc brakes perform better than rim brakes in adverse weather conditions and are able to dissipate heat better than rim brakes. The 2020 Orbea Orca M20iLTD-D Bike is designed for racing and cutting through the wind. It has a carbon frame with full internal cable routing. The frame uses thru-axles on the front and rear for stiffer and more responsive steering.
