inexpensive but effective hanger alignment tool

[AngryScientist]

Full story to follow, but i had an absolutely excellent ride yesterday, right up until everything went beyond wrong. Of course this happens literally miles outside of cell phone cover....

Anyway....


Is the park tool the one to get. not interested in springing for a Cadillac model.

A few spare hangars were my solution to keeping that large tool out of my toolbox. That changes when the Der hangars aren't interchangeable.

If budget is top of mind, get a M10x1 bolt, something 100mm long or so and a pair of nuts. Run the nuts onto the bolt until there's ~10mm on the end. Lock them down and then you can thread that into the hanger and then you have a reference and a handle to bend it back. No it's not as accurate as our HAG but it's ~$3 at the local Ace and it's comparable to the staple tool for this job.

That said, I feel like Campagnolo RD's benefit the most from a truly straight hanger. Their drivetrain in general doesn't have as much play built into it, especially at the RD. So that last 2mm of hanger alignment can really benefit those systems IMPO.

Good to hear you were able to walk, but of course the shoes and no cell service suck!

If you carried a chain tool and/or a spare quick-link, you could have converted your bike into a single speed instead of walking. I've snapped off derailleurs a few times on my MTB, and never had to walk out of the woods.

Or this is if you don't want to fiddle with it and are willing to pay a few bucks more.

Order new hanger or two.

Cold setting 6-7k alloy hanger?? I wonder why it did not do it's job and give up it's life before loss of RD. like it is supposed to do??

yea, i'm going to do that, if this one is not straight i'm not going to try and bend it. i also wondered why it didnt go first.

Wonder if the Wolftooth added another fulcrum, adding more leverage on the RD. If I remembered my structures calculations, I could probably figure out where exactly the max loads are on that setup, but it's been more than a decade since I've had to do that.

I used to use a steel bolt and a pair of vice grips. Now I have a HAG. Much nicer. But that ebay thing looks like a slick cheap option.
