At this point I feel like I got half a bike mechanics education from this channel. Honestly it's even working for them. Whenever I buy new bike tools I always look for park tool stuff because 1. I know the tools are high quality. 2. I'm thankful for all the free high quality information they provide on YouTube.

You can tell a lot of work was put into this video. Keep it up guys, we really appreciate it!

4:56 This is the best instruction i've ever seen! Nice graphics team

[Frostbiker]

And this is why I buy Park Tool. Many thanks for explaining things succinctly.

[sygad]

wow, ALL youtube instructional videos should take note, THIS is how it's done, excellent work and thank you for such a great tutorial

[PRH]

Thanks. Now it’s clear to me how to ID a worn rotor that needs to be replaced. Good stuff…!

[RobMacKendrick]

Just adding my props. This channel rocks, and thanks to you guys, a guy who despises disc brakes (me) has been able to coexist with them with no more than the government-mandated amount of swearing.

[fretboardrunner]

I buy tools from you just to thank you for these videos.

[kswsquared]

The only instructional video series I regularly binge-watch.

[gopromountainbike]

Mine is 160 180 my mountain bike is brand new hydraulic just be careful they have make different design of rotors awesome video it makes my day even better

It is also very important to establish a good rapport between the bike mechanic, the tools and even the bike itself as can be observed by the bike mechanic quietly establishing his displeasure of the lack of cooperation from the other two at 9:05

[MaquinasDePalomitas]

Super thorough!! You guys even covered adapters, which is what I was looking for, covered the adapter type I bought, plus the bonus tip at the end about caliper alignment.

[kaltonian]

thanks park tools, i did wonder if possible to change from single centre locking to the 5 bolt locking system...and now i know without having to over spend,
thank you very much PT

[whatyoudo]

probably the best bike work vids on the net!

[scottyfpv]

My rotor got mineral oil on it. And I stripped the bolts. So I'm on the verge of a mental breakdown over here. 🙃

[PatrickDuganOFFICIAL]

This is really good, and so detailed it made me realize I should just bring my bike to the shop for this work!

[francescodiprisco]

Best video tutorial ... as usual by Park Tool staff. Thanks!

[genedillman]

Thanks for the tip on using the Loc-tite.

Incredibly well put together video. I have the center lock version disc which needs the external tool. And just to let you guys know, that thing absolutely sucks. I have a tool (not Park Tool, but a cheap chinese one), and it's impossible to remove, as soon as I try turning, the goddamn tool just pops off. I have to take the whole bike to the bike shop. The old school 6 bolt system is just sooo much better, I don't know why the hell did Shimano feel like he needed to reinvent the wheel, and make the whole thing worse, needing extra tools and such.
