Bicycle brake assembly

摘要

Various bicycle brake assemblies are described. In some embodiments, a bicycle brake assembly for applying a braking force to a wheel comprises a brake arm comprising a frame pivot joint and a brake pad pivot joint, the frame pivot joint configured to pivotally connect the brake arm to a bicycle frame to enable pivoting of the brake arm about a first axis of rotation; and a brake pad pivotally coupled to the brake arm at the brake pad pivot joint to enable pivoting of the brake pad about a second axis of rotation, the brake pad comprising a braking surface for engaging a wheel rim to apply a frictional force to the wheel rim, the frictional force having a frictional direction, wherein the first axis of rotation is not parallel to the frictional direction of the frictional force.

主权项

1. An aerodynamic bicycle brake system for applying a braking force to a wheel, the aerodynamic bicycle brake system comprising:
a bicycle frame having a seat tube including upper and lower ends, at least one seat stay connected to the seat tube adjacent the seat tube upper end and at least one chainstay connected to the seat tube adjacent the seat tube lower end; a rear brake arm pivotally coupled to the seat tube intermediate the seat tube upper and lower ends; and a rear brake pad coupled to the rear brake arm, the rear brake pad comprising a rear braking surface positioned to engage a rear wheel rim when the rear brake arm pivots in a direction toward the rear wheel rim, wherein the seat tube comprises an integral air deflector positioned adjacent the rear brake arm, the air deflector shaped to reduce an aerodynamic footprint of the rear brake arm.
