Excellent video!!
Hands down! The best quality videos you can find on YouTube! Thanks a lot guys!
Excellent video
when the cable on the front derailleur snapped, i cut the cable so it won’t poke through my legs and to make me go faster i put a rock in between the pivot where it shifts. i was able to use the second gear in the front, it got me home fast and quickly.
Thanks so much for your help
Hi,
Thank you very much for the explanation.
I have a question. Is it ok to have just front gears to a bike?
Thanks in advance.
had to replace a broken rear derailleur cable and had never done either front or rear adjustments before, the Park Tool videos are great, awesome overlay graphics to show how the mechanisms are supposed to move and align, great job! I can add derailleur tune-ups to my repairs resume, thanks
Thanks calvin! You helped me do work easier!
Great video thanks
Thanks mate, this was excellent, was able to go through three bikes and redo all the front derailleurs. Cheers!
I was looking for a solution with my derailleur problem, you know I´m an atheist, but now I found GOD.
Thank you so much! I took my bike to so many shops and I could never get my adjustments right. After watching a few of your videos I was able to get everything just perfect.
You are awesome sir! Thank you so much😃
There is no barrel adjuster on my bike.. How can I adjust the cable length in this case? how does it change the derailleur cable tension adjustment? 🙁 thank you
This guy is awesome! ^_^
THNX a million!! the most intelligible explanation of the topic so far
I can go to 2nd and 3rd gear on my front derailleur easily but wont get back to first what can i do to it i have a rockrider 5.2

Excellent easy to follow instructions.
Thank you!

RECOMMEND !!!!!!!

Great video with very concise instructions and explanations. Thank you so much!!!
It has really helped me to fix my bike by only adjusting the barrel <3
Thank you for posting these videos!
Wow! I’m new at cycling and I find this amazing. Bike anatomy is exciting. 😄
Excellent quality video’s that really help understanding the operation of bike gears and adjustment. Well done Park Tools.
I had to watch the 3:37 portion about 20 times to really understand what was going on. 😂
En español por favor.
Thank you for your video. It is really helpful.
Great video, and had no idea Frank Zappa was an authority on bikes as well!
Your videos are better in every way than the ones I’d watched previously, thank you.
Thank you Mustache Man
Anybody can setup a service center after watching parktool videos
Love to watch your video👌I had same issue and after watching your video I solved my mtb problem thanks to All mighty thank u Park Tool.
4 Bar linkage – engineer
very well explained
On the left Shifter there are numbers 1,2,3. Which ring on the front corresponds with each number?
Great video
Park Tool company is the father I never had!
Absolutely brilliant series of vids.
Thank you!!
High quality videos..subscribed!
The very best bike repair videos, well presented. Excellent professional production .
That was so clear and concise! A video explaining the mechanism so clearly sure goes a longer way than a long video just attacking the adjustment points with no clear reasoning.
