Anyone else ever use the how-to videos on youtube? If you struggle with adjusting a derailluer go give them a try. What was once difficult for me is now so easy.

They supplement a written procedure, and those "how-to" vids frequently omit information or are just plain wrong or use incorrect or un-ideal procedures.

To better understand with some hands on visual yes I did looked up how to adjust on youtube and thats the single reason im able to do it today. Having a manual might be a good thing but its hard to understand with out someone to show you if you have never done it. It took youtube example before I finally fully understood it and I think thats far better than just a manual alone.

Online repair and maintenance videos are the best when I was learning to do stuff to my bikes.
I learned a ton from the late Sheldon Brown too.
