Ja, man kann wahrlich mehr als genug von einer eigentlich guten Sache haben. Die höhere Hebelübersetzung von Aerobremshebeln geht zu Lasten des Zugeinholwegs. Das ist insbesondere bei moderneren [[Low Profile Bremse]]n ein Problem.
Yes, you can have too much of a good thing. The greater mechanical advantage of æro levers comes at the cost of reduced cable travel, especially when they're used with newer "low-profile" cantilevers. If you wind up with insufficient cable travel, you have to choose between having the cables so tight that the brakes drag lightly on the rims even when released, or, having the cables so loose that you can squeeze the levers until they bottom out against the handlebars. Neither of these adjustments is satisfactory.
Wenn man sich mit zu wenig Zugeinholweg abfinden kann, muss man sich entscheiden zwischen hoher SPannung, die zum ständigen Schleifen der Bremsbeläge an der Felge führt oder so loser Zugspannung, dass man die Bremsbeläge kaum bis an die Felge bewegen kann. Keine dieser beiden Einstellmöglichkeiten ist zufriedenstellend.


Since the mechanical advantage of conventional cantilevers can be adjusted, the usual cure is to raise up the cable yoke, as described in my Cantilever Adjustment article. This is generally not a serious problem with the all-important front brake, but the added stretch of a long tandem rear brake cable may preclude a satisfactory adjustment of the rear brake. If the suggestions in my Cantilever Adjustment article don't solve this problem for you, you may need to buy levers made specifically for cantilever use, such as the Dia Compe 287, or convert to a direct-pull system with a pulley.
