Dude! That cutaway explanation was genius.

[paulkrupa]

This is the best video production on that I have seen for bike maintenance. The pace is great, the visual aids are excellent, camera work and audio are very good. And most of all the instructor is very knowledgeable and skilled.
Video tutorial makers: watch and learn.

That cutaway is just perfect. Demystified the crank remover for me. Fabulous. Gives me more confidence to do more of my own maintenance now I understand how the basics work - and save money in the process. Simply the best bicycle "How to" instructions on the web. Top Job.

Needed to replace my bottom bracket so I brought it to reputable bike repair and then later that day, they called to say their usual suppliers do not have the part and I should consider buying a new bike. I took my bike back and called the manufacturer the next morning and within ten minutes I had ordered the part which was delivered 6 days later. Six days without my bike, ugh. Anyways, being of limited means and feeling let down by the bike repair shop, for why didn't they call the manufacturer like I did, I have decide that it is better if I learn how to do this for myself. So, I just want to say a big thank you to you guys for clear and precise explanations.
Cheers

OH MY GOD THANK YOU FOR SHOWING THE INTERNAL WORKINGS WITH THE CRANK REMOVER!

[krollpeter]

This is the most comprehensive yet concise explanation on the entire net regarding 3-piece crank removals, and it's professionally captured!
Good maintenance is helping not only to safe money but also is good for the environment.

OMG! I've watched a bunch of people doing this operation and none of them show the detail or explain it in any way. But you? Cut-away view of the whole thing. Brilliant! They should ALL be linking to you.

[michaelcantu]

Appreciate the quality of the video and information. Couldn’t have completed my repair without this

[richjenn]

Totally brilliant! Never seen such a clear exposition, superb detail, common sense about arm positioning, what a contrast to most of the shaky ill-lit stuff on YouTube!

Thanks SO much!

[mikeycuzz]

awesome! this easy to follow demonstration made my day after I was super annoyed having to do this with a brand new bike. fortunately, I found this video right before I started throwing tools!

[haseebahmed]

The cross section demo was out of this world!

[ctvwrest]

The best video for crank install/removal on YouTube! Thanks!

[pyramidion]

Calvin jones is the man I owe him at least a hundred beers now with all he has taught me from these videos

[vvvvali]

Amazing. Cutting the pedal arm to see inside was brilliant.

[JohnySeen]

It's wicked to see those demonstrations. Thanks a lot for showing it so clearly and straight forward. I had no idea there were this many variations with the bottom bracket. Bloody manufacturers should stick to one and keep it simple.

[Henri-qp]

After searching for hours everywhere, thank you so much for this tutorial ! This is the only video I've found explaining that there is a small and a bigger driver foot on the CWP-7 as the tool comes with the smaller one attached by default.

[Corvin]

You are the best! Thanks so much! Replacing old rusty drivetrain was a breeze. Bought a parktool crank puller out of gratitude
