SRAM Force 22 Front Derailleur;

The latest iteration of SRAM's Force 22 Front Derailleur boasts two properties that we typically don't see together: accommodating flexibility and unyielding stiffness. The derailleur's willingness to accommodate is the result of SRAM's Yaw technology, which has only just trickled-down to the Force level. Yaw is the equivalent of an auto-trim feature that keeps the derailleur cage aligned with the chain as it moves through the sprockets, making for a truly 22-speed groupset by virtually eliminating chain rub. The derailleur's stiffness comes courtesy of the aluminum and steel body. The incorporation of steel makes for an irresistible force to quickly shift the chain up or down without yielding valuable moments of response time while waiting for a flexing cage to finish throwing the chain--think of it as the opposite of the Close Door buttons on elevators. In case you get a little too overzealous with its stiff shifting, the Force Derailleur also features a removable Chain Keeper to help keep you from throwing your chain while shifting in response to an attack.
