Bent but cheap: To fix or return?

Got these super-cheap 180mm Odyssey cranks, for a rider:

They're also twisted, but I don't mind that:

When I was a kid we used to put a pipe on the end of cranks to bend them back. Now that I'm no longer a kid, something tells me that's a horrible thing to do to a frame.

So these cost me less than $10. Knowing that I probably won't find any straight cranks this old for similar money, should I fix them or return them?

Bend em back! The body is very flexible and you wont bend em again from riding or smaller jumps. If they do bend it will be from impact and the cranls will be the least of your worries. Ive bent a few cranks back in my time and dont remember ever rebending the same cranks twice.

I'd say send them to the recycle bin.

Why would I want to do that? The guy said they weren't bent, so my only options are to fix or return. I can't just let him off the hook by tossing them and letting him keep the money.

Yea why would you toss them? I don't have experience with bending cranks, but it sounds fairly simple so I say go for it smile

Re: Bent but cheap: To fix or return?

once its been bent,the metal has fatigued.
when you bend it back to straight,its permanently fatigued.
i wouldnt recommend riding bent cranks,at all,ever.

and if you are in need,ill give you a crank arm a tioga task force thats not bent/new,never been used.
they have pink paint thats been shelf worn off.
best bet is to remove the paint n theyll be fresh shiny chrome.
ill send a pic if you want and all i ask is just pay the shipping to you.
always better off to be safe then sorry.
just lmk.

oh, i missed that part. Didn't realize you had them shipped to you. I'd send them back i guess. I wouldn't bend them back as the steel is now compromised and weak.

Actually it work hardens which means its not harder and probably wont bend again. Straighten em out.

If you post sometime down the road saying they snapped or rebent i will be super super surprised.

Exactly, bend them back the best you can and they will be just fine. Ive done a few the hardest part is just eyeing them up but have never had them bend back. Do NOT heat them just do the vise pipe thing.

A vice! I have one of those...I think it would be easier just to mount them in a frame and use a pipe like when I was a kid but then again, it's a horrible thing to do to a frame.

Need is such a strong term since I already have a perfect set of 170's and a couple mediocre 175's. Want is more accurate since I'd really like longer cranks. I just needed to be honest about that before hitting you up smile
