Oxford Cycle Replaceable Alloy Gear Hanger Dropout Type F - MARIN, SCHWINN

The gear hanger is designed to bend or break and so protect damage to the frame. Often simple actions such as resting the bike gear side down in the back of your car so the weight is on the rear mechanism, or leaning other bikes onto your bike so their weight is on the rear mechanism, can cause a bent or broke gear hanger. Typical symptoms of a bent gear hanger are slow or hesitant upshifts and downshifts.
