I bent the shifter lever on my Deore shifter mech and the bottom lever that would shift me into an easier gear is running into the lever above it when the bottom lever gets pressed in. If I try and move the top lever out of the way, I can successfully move the bottom lever and get clean shifts with the crisp click every time. Otherwise the bottom lever pushes on the top lever and the shift doesn’t complete. Hopefully the pictures show the misalignment.

Anyone have any good ideas on getting the lever bent back straight? I’m a decently strong guy and I’m trying pretty damn hard to straighten it back out and it’s not moving. I tried removing the bottom cover from the mech as well to use pliers to try and straighten it out to no avail.

It’s the bottom lever that is bent right?

You are just going to have to find some way to apply leverage to the thumb lever, I.e., bigger wrench or pliers.

An approximately 30cm length of metal or stout plastic tube that just slips over the shift lever is ideal.

Be aware that the aluminum lever is going to be weaker at the spot it was bent and bent back.

  • I will give that a try. Need to make it to the hardware store to find something that length to add leverage. Just trying anything I can to not have to replace an otherwise perfectly functioning shifter!

  • A long screwdriver should do the trick, using the handlebar as a fulcrum/pivot.

I had exactly the same problem, bent it in a crash. I took it apart, used pliers, tried my own strength... nothing worked. Then I tried the metal pipe option mentioned here, and it worked like a charm. I had a 1 meter piece of pipe lying in the garage. Got it bent back in seconds, working perfectly now. I suppose its weaker now but seems strong, if it breaks now then thats okay, I can get a new one then. But for now I am happy I have prolonged its lifespan.

It is not necessary to look for a metal pipe of the required diameter. Any glass bottle with a standard narrow neck will do (For example, a beer bottle). Its neck is strong enough and has the required diameter to insert the shift lever into it. And a convenient extension will allow you to adjust the depth of threading the bottle onto the switch in order to more conveniently adjust the lever and the place where the force is applied.

    This answer refers to using a glass bottle. This seems odd if not even dangerous. @DoNuT I wonder if this could be a translation mishap?

    Hi! Sorry for the Russian comment. I did not think that my comment would cause such a heated discussion=D. In the age of the Internet and the built-in translator in almost any browser, I did not think that I needed to write in my crooked English). As for the glass bottle, you understood everything correctly. It's strong enough to break in your hand! But if you are afraid, you can use the seatpost tube)
