Fixing A Sagging Bike Chain

I bought a vintage Atala road bike that had a drooping, saggy chain. The chain sagged to the point to wear it was hitting the chain stay. I walk through the steps to diagnose and fix the problem.

  1. I accidentally made my chain a little too short when I put a long cage derailleur on my bike the other day but I was able to add the links needed back again without a master link or anything. It's been holding up fine for the last couple hundred miles, been checking it regularly. It was not easy to to add the links back again, and it certainly does pay to measure twice and break it once.

  2. I know this is an older video, but just a note of thanks! Many times, now, your videos have given the information and confidence to successfully make my own bike repairs and save many dollars. Thank you!

  3. Always a pleasure watching your videos Sir, you explain the process extremely well in all your maintenance videos and coming back to cycling after many years it's good to do your own maintenance as part of the cycling experience and doing it safely of course… are my go to guide when I need information with cycle maintenance….brilliant work…and I thank you for this… proved a great service and may it continue.

  4. Very helpful. Thanks for the video!

  5. Beautiful bike RJ! Love the chrome details on the white frame.

  6. is it possible to change 6 speed geared bicycle to 12 speed

  7. watch out for heavily worn chainrings & cassette with the chain being 100% worn! :O

  8. Where do you get your used bikes to restore/repair? Great video keep it up.

  9. Would have been interesting to see both chains next to each other and show the increase in length from stretch.

  10. Nice work RJ

  11. hey RJ, I think I noticed that one of the rear pulleys has a tooth missing. just check it before you call the bike completely finished

  12. Hey RJ I was wondering if you could do a video on how to appropriately/best store a bike outside? I live in England so we experience a great deal of rain and cold weather (in the winter at least) and atm I'm leaving my bike chained up outside my house, exposed, most likely starting to rust. So a reply or even better a video would be greatly appreciated! Cheers!

  13. hello , I just put new air in my tire and the pedals move fine and the back wheel moves fine but the front wheel won't move so I can't ride it how do I fix this ?

  14. Thanks for posting. Another good video.

  15. Nicely done.
    Merry Christmas!

  16. I like the process in which you went through to determine the right fix.Thanks for posting this instructional video.

  17. Hi RJ
    How abort the rear cocs, if the chain is that worn, the cassette would be just as worn and would potentially ruin the chain i no time?
