Exposed brake calipers create turbulence that costs watts at race speeds. The Cervelo P5 Front Brake Cover wraps around the Magura hydraulic rim brake on P5 frames, smoothing the airflow through the fork crown area where the front brake would otherwise disrupt the carefully sculpted aerodynamic profile. The cover isn't optional cosmetics—it's an integral part of the P5's aero system that Cervelo engineered into the frame design from the start.

The covers come in left and right sides sold separately, which matters because the two halves aren't interchangeable. Each side is shaped to wrap its respective brake arm and meet in the middle, creating a unified fairing that blends with the fork legs and nose cone. The sculpted profile follows the fork's airfoil shape rather than simply boxing out the brake mechanism, maintaining laminar flow as air passes through the front end of the bike.

Travel and handling take a toll on these covers over time. The thin plastic construction that makes them aerodynamically efficient also makes them vulnerable to cracks from bike case impacts or shop stand contact. If your covers show cracks or chips, replacement restores the aero performance you paid for when you bought a P5. Running without covers or with damaged covers defeats the purpose of riding one of the most aerodynamically refined triathlon bikes available.... Read More
