If it was steel I wouldn't worry, but aluminum can have issues. Seems to me that only the front part of the dropout has seen any bend at all. It's not going to get any further significant stress. Axle loads are upwards into the dropout slot, placing the top of the slot in compression, so there won't be any worries about generating a crack. Clamping loads are minor and well supported. IOW, I can't visualize a likely cause of any failure of consequence. Even if I had to "unbend" it a little bit to get clearance for the QR nut, I wouldn't worry as long as it didn't crack during the unbending process. But my first choice would be to just file and ride. - Frank Krygowski |

My wife's brand new Klein. A well meaning friend tried to help her load it on her car and dropped it on the front dropout. The dropout's bent and the axle won't fit. I think it might be possible to bend it back into shape or maybe even file it because the axle almost fits, but I'm worried that the aluminum might be weakened and I don't really like the prospect of the dropout failing and her front wheel falling off on a fast descent. I uploaded a picture comparing the damaged dropout to the undamaged one at: http://www.westiesd.com/posting/Fork.jpg I think it illustrates the damage pretty well. Does it look like it can be repaired? I'd rather be safe than sorry. Thanks very much for any help. just use a file and make the slot wide enough to fit the axle again - you'll be fine. try not to make any gouges on the inside of the slot though. |

Not so with aluminum, which will crack when bent. You cannot see the cracks, but they are there. You might even want to cut off one side of one of the dropouts, so nobody else picks it out of the trash and tries to use it. ~ |
