[@polaris911]

great advice. I tried bending my hanger back by hand and got it straight, but it snapped a couple rides later

[@JoeBob79569]

I'll give this a thumbs up just for you saying "derailer" like a proper person without an extra "eeuu" near the end.
Hearing people say "derailleeuur" really grinds my gears for some reason!

[@manojgaonkar5221]

Thanks for the detailed explanation.

[@burple65]

Excellent video. Great job of presenting the facts.

[@vasiligarcia8403]

Muy buen video ,aprendi como se hace ,gracias.Saludos

[@m1cannas]

Please make a video on how to replace the gear cables of the gear switches.

[@Maik1968]

That is awesome to know. I wondered what this thing is for. Thanks and have a nice weekend. Greetings from Germany 👍🌞💪

[@legacymedia3993]

Happy to see u bro🫂

[@814Taylor]

Great video and information. Thanks

[@Jamesthebikeguy]

Thanks for watching!

[@JamyRyals]

This video was great, I’m in need of this exact fix on my MTB... from your description I suspect the horizontal alignment is off. Ordering the tool now, thanks James!

[@Jamesthebikeguy]

Nice, let me know how it turns out.

[@JamyRyals]

@@Jamesthebikeguy I finally got the tool and definitely had some adjustments to align my hanger. Now I’m able to shift up and down the whole cassette without any weird skipping or rubbing! Huge thanks man, I was really discouraged about doing my own work. Felt like I couldnt even index my gears right!

[@dkw4par]

Awesome on the 180 degree adjustment points. Cheers!

[@Jamesthebikeguy]

Cheers

[@harrygrimley4352]

I broke one of those recently and it took about four weeks for the shop to find one

[@alberoDiSpazio]

That is one crazy tool.

[@MountainParameters]

Thanks for this. When I reattach my derailleur to the hanger, it pivots around the mount screw and it seems there are different angles on the Y axis that I can mount it at. At this point I am unsure of how to remount the XT derailleur onto the hanger at the correct angle.

[@leftyseel8658]

Bought a new hanger. It’s a Union brand, GH-192 for my CAAD8. I still need to align it? I thought i just need to put the screws in, put the rd and wheel back in, adjust the limit and b screws and indexing if necessary.

[@masaharumorimoto4761]

Good video! I totally just said fuck it and bought a new NorthShoreBillet hanger, might as well have a pimped out hanger lol.

[@meshark_t]

What's the website link for hangers, plz.

[@ezatialfred7084]

Does every geared bicycle have derailleur hanger?
I don't see any like that on my bicycle

[@Sangram-IND]

Brooooo ❤️❤️❤️❤️❤️🔥🔥🔥👍

[@Jamesthebikeguy]

Cheers 🍻

[@harrygrimley4352]

My front disk brake grabs real good my back not so much. I've cleaned it with alcohol and no improvement. How do I get my back brake to grab better?

[@jfrtbikgkdhjbeep9974]

tainted pads, may need to clean or replace the pads ... try spraying the rotor and pads with a solution of dishwashing soap and water

[@zerrocoolcp]

Great vid...for future vid how about a conversion from 2×8 to a 1×12 Drivetrain. What to consider and pro/cons of the change.

[@germaincousineau8608]

1x is easier because you don’t have to think about choosing between the front chainrings. The only cons is cassette cogs usually have bigger jump(11-13-15 etc) For a recreational rider like me,you get used to it. I hope it helps. 😉

[@triciamcintyre4947]

I wish I had your patience.🚴🤷

[@legacymedia3993]

Can i get a giant escape 3 derailleur hunger am in Uganda

[@attybong]

just like promises, derailleur hangers are made to be broken (for the protection of the frame of course) .. that's all

[@garypostell5268]

Pays to have a spare

[@harrygrimley4352]

Great video. But you used the word parallelogram. Wow.

[@user-my8gx3rp2j]

This is disgusting. I do not know the reason for these prices. It is just a small piece of aluminum that does not even take time to manufacture. Also, companies are deliberately making complex designs so that one is not made manually and forcing people to buy one at an expensive price in exchange for a piece that did not cost The company is more than one dollar

[@jfrtbikgkdhjbeep9974]

right, it is expenaive labor and parts costs .... i know
