    How BENT of a Chainring is OKAY?

    Somehow I bent my chainring, probably the stupid crash I suffered recently.

    Anyways, eyeballing it, the ring is about 2mm off from straight at its pinnacle.

    Is it okay to just leave it alone? I mean, I don't feel it while pedaling. However, if you think it's better to bend it back, what is the best method to bend the chainring back to straight?

    Much thanks!

    Dear Natalie, please ask Anakin to use the Force to help you bend it back. If he's not around, I am sure 3PO can help as well. He may look like s sissy, but he is in fact, a very strong droid.

    If any of these options don't work, please keep in mind that your son, Luke, and your daughter, Leah, will make out.

    God forbid that I actually continue communication with anyone (accept Ewen of course) from those pathetic sans Blockbuster attempts at filmmaking. But hey, I take responsibility for stupid acting, though in my defense I just did what George told me to. Does it matter that I was dropping ludes while drunk? Pretty pathetic, I know, but atleast it was consensual. I just groped myself, happy now!

    Ps. The chainring remains bent.

    That's the tool I've used before to straighten rings.

    Aluminum - leave it alone...

    Bent, ovalized, cracked, warped, whatever = garbage. Replace it.

    Bent steel can and will literally fold over on itself. There are quite a few anecdotal stories involving Surly rings to this effect.

    Bent/fatigued aluminum will just crack and break.

    Either of the above usually when you are standing on the pedals on some really steep grade. Why risk it?

    Great tool! The ring straightener is good too.

    As for V for Vendetta, I don't remember making that one. I mean, she looks like me, sounds like me, but again, when you're doing loads of "Kosher" drugs, well, somethings just slip the mind.

    Agreed. I'm just conservative, not one to be wasteful.

    Yeah, and you said it right, "Why risk it?" ... Word.

    Thanks!

    I thought for sure that would link to a picture of a hammer.

    The best piece of kit for straightening chainrings is a u-lock. But I'm good at beating the crap out of something because I've had a lot of practice.

    Remember that white outfit at the end of Star Wars: Episode II? Cause I still do.
