Das 1x1 der Felgenbremsen: Unterschied zwischen den Versionen

Preferably, every part of a rim-brake system is rigid except the brake shoes. Their compressibility allows them to conform to the shape of the rim and to take up the motion of the brake levers. If, on the other hand, the brake arms are flimsy and flexy, as on cheap long-reach sidepull caliper brakes, there is no way the brakes can develop enough "power". Most of the motion of the brake levers is wasted in flexing the arms. If the mechanical advantage is high, the brake lever will go to the handlebar before the brake shoes grip the rim very hard. If the mechanical advantage is low, the feel at the levers will be harder, but the brake will never develop enough grip.
