Cassette Removal & Installation
Cassette Removal & Installation
Calvin demonstrates how to remove and install cassette cogs and choose the correct lockring tool.
Important note!
There’s another cog system called a “freewheel”, and the procedures in this video are for cassette systems, not freewheel systems.
If you’re not sure what you’ve got, watch this other video to help you determine which is which.

Why are we doing this? Sprocket teeth wear over time and no longer engage the chain leading to poor drivetrain train performance and chain skipping. This procedure is also used when replacing the cassette for an upgrade or to changing gear ratios.

i really love this stoic clean and precise informations
What dumb ass gave this a thumbs down? A demonstration does not get any easier. Thanks Calvin
Whenever I get the blues I click on over to Park Tool and re-watch my favorite Calvin tutorials. Boom! Blues are gone.
anyone else having trouble getting it loose?
So u need FR5 and you can make chain whip from old chain.
Great video, very clear and great presentation. I did chuckle when Calvin said to give the vid a thumbs up…and failed to do a thumbs up lol 🙂
calvin is G.O.A.T
Park Tools #1💖👍👍👍
My spring on the rear wheel is stuck on the drive side. It is possibly entered the wrong way with the narrow side out by an incompetent mechanic. If I yank it with a pair of pliers it might get deshaped. Is there any tips or tricks to take it out? Not really related to this but would be grateful if I get some help here. By the way, it doesn’t affect my wheel mounting or movement.
the last 2 rings (the smaller ones) are independent of the cassette body. Do the teeth on the last rings need to be aligned with the rest of the teeth on the cassette in a certain way ? Other videos out there speak of such a process…
I got lower back pain just from watching the cassette removal procedure
Great as always
wax on wax off lol.
Calvin is the absolute Best, if not he is the Master Jedi of bike repair…
me gustaria comprar herramientas
This video is exactly what I was looking for… thanks so much…
Yet another thorough, comprehensive, well-paced, and detailed Park Tool instructional video. Thanks so much, Park Tool. You’re awesome, Calvin!
Well filmed, very informative. Two thumbs up
This video contains zero BS. I’m really satisfied.
Hi. Can I replace my ultegra to 105 cassette? Same speed and size. If yes, any adjustment required? Thanks
How can I order this tools and installation
Hi for installation : should i wipe off old grease with alcohol first or simply reapply new grease to the freebody hub?
Another great video! thanks!
Anyone know if bicycle shops sells them?
Body weight technique at 4:07 – Far better to arrange the two tools at a narrow angle to each other, then squeeze together with both hands. It is very difficult to bring full body weight to bear. Moreover, for the vast majority of people, even full body weight won’t nearly match the force that can be exerted by the squeeze technique.
For once my body weight will be an advantage …
Thank you. Very clear, easy to follow instructions.
Thanks, for all your informative hints, tips, and knowledge.
This guy knows his stuff. Excellent teacher in his field.
You are the number one on the business
I don’t use cassettes! I graduated to CDs years ago! 😛
Will repeated removal and installation cause damage to the lockring or the first cog? Its really nice to be able to get the cogs off because they fit in my ultrasonic cleaner haha
I noticed Calvin using the chainwhip on the smallest cog. I always used the largest cog because I am probably doing it wrong as is my tradition with anything mechanical. I figured that there would be less force on the chainwhip and thus easier to use. Next time Im trying the small one.
Videos like this make me want to take apart my bike "just because" :).
Great tutorial Calvin. Worked a treat for removing the Dork Disc… i went to replace my SRAM PG-1130 with another SRAM PG-1130 and it doesn’t fit??? Really baffling the only difference is mine was a black 11-42t my new one is a silver 11-36t I’m unable to tighten the lock nut with the smallest cog on it. Any ideas anyone?
i got an 29ER WTB WHEELS WITH SRAM INTEGRATED FREE HUB 10 SPEED AND UP GRADE WITH NX EAGLE GROUP SET – THE 12 SPEED CASSETTE FIT PERFECT BUT ITS LOOSE ON THE FREE HUB – DO I NEED TO ADD AN SPACER
thanks luigi
I was trying to get a tape out my old music system and ended here… 😂
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Very helpful 👍🏻
how about casette on a voltage gt 500 scooter cant find anywhere only bikes .please helpl cant get off hub. thanks
Calvin is so damn sexy!
So all I need to install the cassette is the lockring tool ? No chain whip required ?
Merry Christmas Park Tool u.s.a 👍
what type of lube is that?
Calvin…please don’t say shram.
One of your better videos
Your videos are great and super easy to follow, thank you!
