      I came to comment section to say the same thing...freakin genius. Prior to this i was using i hammer to flatten it on the concrete.. didn't work. This seems better than the expensive tool.
      Much Thanks!!!!

    I just went back to this video. I watched it quite some time ago. I'm on a MTB vacation and shifting wasn't great at all. After checking everything twice and a third time... without fixing the issue and owning a lot of tools but no derailleur hanger adjustment tool I thought I had lucked out... Remembering this video and my son (the only one) having the old qr. I took his rear wheel and fixed the derailleur hanger! Shifting... Flawless😁👍. Thank you so much. I think my wife is even happier than me when I was driving her crazy with my "bike fixin' stuff". Thanks again man😀

    Almost a 5-year-old video, but the first time I'd seen it. RJ never ceases to amaze me with great repair guidance. I'm making this exact repair on a Cannondale aluminum alloy frame. Seems to have worked just fine, despite not being steel.

  • @demondroid666
    @demondroid666 6 ปีที่แล้ว +8

    Awesome tip for professional roadside repair! Another tip: for a rough eyeball adjustment, instead of wrench use a L-shaped allen key in the derailleur fastener. No need to remove wheel or derailleur and you can use the cage for reference.

      RJ’s and the Park Tools vids are a good pairing actually.

  • @forestfriend9265
    @forestfriend9265 2 ปีที่แล้ว

    Another one of the grateful comments, thank you so much for the video!
    My bike fell over recently, after that shifting got inaccurate and the chain got stuck between cassette and spokes.
    This method worked really well, only challenge was cross threading, which happened when trying to work with the bike upside down, but in the bike stand I could get it in straight. It took some time to get the distance even because the wheels don't overlap, having a transparent ruler helped a bit when measuring at different places. Eventually it turned out great 👍👍👍!!!
    Update after a few days of riding: I got the impression that the derailleur is working smoother than ever now, maybe the bike even came with the hanger a little bent in the box. Big thanks for the video!

  • @Triplex5014

    @petrbursik6473 5 ปีที่แล้ว +2

    Awesome! Thank you, sir!
    Was looking all over my place to look for something that screws in there and must have walked right past my old rear wheel more than hundred of times. It was just there laughing at me :D Also figured out a neat trick to visualize the wheel plane - get a thread and wind it tight over the wheel (the one that's on the bike :) ) in a couple of directions. I was straightening a hanger on a 29" bike with a 26" wheel so I could measure the distance to the thread in all directions.
    This saved my riding for ~2 months until my replacement hangers arrive from China :o

  • @DEAR7340
    @DEAR7340 ปีที่แล้ว

    This really helped. I tried the adjustable wrench method, but I could only guess at the plane that the hanger was bent in. Using a spare wheel, I was able to see what was needed much more clearly, and I didn't have to pull the trigger on buying an expensive tool that I would rarely use.

    I was convinced that the pivots in my rear derailleur were shot as I felt some play in the cage, the pulleys appeared misaligned, and the chain was a bit noisy and skipped on occasion. I decided to take a look at the hanger- sure enough, it was bent. I would have never thought to bend it with the wheel reversed but the crescent wrench trick worked great! Thanks!

    @Jordanmilo 2 ปีที่แล้ว

    Can’t get my vintage brifter conversion to shift properly so I’m going to try this alignment method. Thanks for posting this brilliant idea! FOLLOW UP: I didn't have a spare wheel in the same size (700C) as the one on the bike I'm working on; I only had a 26" MTB wheel, and since the dropout is lowers the "gauge" wheel anyway, I couldn't get this to work for me. So if you're going to try this method you'll need a wheel the same size as the one of the bike you're fixing.
