About: I like to tinker with just about anything, sometimes it works out in the end. Have fun looking at the projects, try tearing something open and let me know how it goes. cheers, -Joe

This is a quick instructables on how to install a cassette on bike.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Tools

  • wrench
  • cassette tool
  • chain whip

Most people will need a shimano hyperglide tool, get the park one, it's $5 or so.

Step 2: Whip It Good

Put the cassette tool on, I use the quick release to hold it in place. you know, so it does not fly off and you end up wrecking your knuckles.

Position the chain whip on the 3rd or 4th cog, wrap the loose chain part around the cog, use the fixed chain portion to hold the cassette in place.

Then use your wrench to unscrew the lock ring. You really only need to use the wrench to 'break it.', then you can do the rest by hand.

Step 3: Remove

Unscrew the lock ring it by hand. Then pull the cassette off.

The ramps on the cogs should face out when you put it back together.

Step 4: Reverse It

Reverse it all and put it back on the hub. Notice it only fits
one one way.

The lock ring thing has a super thin washer. Don't lose it!

Also grease the heck out of those threads, or it will be a pain to get off.

Step 5: No Whip

Now yard on that sucker.

The best way is to use the wheel as a big lever like pictured.

Go ride, have fun.

What have I learned from this instructables? I need to go to the gym and get some arm muscles...

    Read This BEFORE You Buy the HyperGlide lockring Removal Tool!

    The tool for lockring removal of HyperGlide lockrings recommended by Shimano is the TL-HG15. However you may not need one!

    If you have the TL-FW30 used for removal of Shimano freewheels. It apparently fits all of Shimano's HyperGlide lockrings!

    I found this out out by accident, because I had an 8 speed freewheel on my bike and when I came to replace it, I found that these are available, but the sprocket choice is very limited because the unsupported axle leads to bent or broken axles. I therefore was effectively forced to go down the freehub and cassette route. I ordered the tool only to find it was out of stock. I rummaged in my old bike tools bin and found a TL-FW30, it looked promising tried it and it fitted!

    I then googled for the part number and found this link which confirmed that it was suitable.

    Alternative to the Park chain-whip is to have some old chain clamped in a pair of vise-grips after wrapping it around the cog (for us who are THAT poor :P). Clamp both ends of the chain, using the chain to prevent damage from the pliers. Genuine vise-grips work best for this due to their unique shape. ««Do not use this method for chain you intend to re-use»» Practice and uncommon-sense will show you the way. This is why I never throw out old chain, and I have as many chain-whips as I need. Great instructable, but I do agree that cleaning parts prior to photography does make them more photogenic and visible, however they are not terribly dirty in the first place, so I don't see why others have trouble seeing it.. In mine, I actually did the photography in reverse, after I had already cleaned the parts, and I was actually photographing assembly for the disassembly portion.

    Some _constructive_ criticism...

    The steps you documented are:
    • list tools
    • loosen lockring
    • unscrew lockring by hand
    • look at the lockring
    • put the lockring back

    You have zero pictures about actually removing or installing the cassette. Please add these steps or rename/remove this instructable.

    When taking pictures, turn on all lights or take the picture in a properly lit place. The lighting in your garage is inadequate. A cheap 250W halogen construction light and an old white bed sheet goes a long way.

    It would be a good idea to wash the bike parts before making an instructable. The dirty parts make the pictures look even darker and make the instructable look very hastily made. First do the steps in your instructable for yourself, then wash parts and only then do the instructable for your _audience_.

    Perhaps it was updated as a response to your comment but... Step 3's main picture looks like someone seconds away from physically removing the gears. What would a picture of removal look like other than the bike (sans cassette) on one side of the image and the joe's hand holding the cassette on the other. The lack of that picture doesn't make this Instructable weak. All the images look fine to me; the things he intended to show (use of hyperglide tool, what the washers look like, and re-tightening the lock ring) are clear. I think the bike shop background gives him a little more credibility than would a light tent. What's dirty? The cassette before removal, but you remove it to clean it up (a guess, I actually have no clue). That last sentence is awesome, a great tip for all writers. Maybe joe and I think similarly (he's flattered, I know) so this Instructable "clicks" more for me than for you...I dunno. But overall it's fantastic to see some specific, useful critiques of someone's presentation here on this site. I hope you take the time someday to delve into my projects and give some advice. And why the hell is your handle "Visitor"!? You've got the bike frame trebuchet, the most underrated project on the whole site!

    I manages to make my own chain wip with an old wrench and some chain. It works suprisingly well. Thanks for showing all the n00bs out there what a cassette is!

    :) I had the same issue as dorx. I thought "Cool! Maybe he's using the gears to power a cassette deck. Slow down, and the music slows down. Speed up, and the music speeds up."
