Excellent article! Calvin is arguably the most knowledgable, articulate and humorous bike mechanic out there.
I guess Im randomly asking but does anyone know a way to get back into an Instagram account?
I stupidly forgot my password. I would appreciate any assistance you can give me
@Cristian Easton Instablaster :)
@Theo Sergio thanks for your reply. I got to the site on google and I'm trying it out now.
Takes a while so I will reply here later when my account password hopefully is recovered.
@Theo Sergio It worked and I now got access to my account again. I am so happy:D
Thank you so much, you really help me out :D
@Cristian Easton glad I could help =)
Calvin is an excellent teacher and his videos have helped me a lot.
Love you all videos. As a beginner cyclist as I am getting older, you all saved me so much money, but also helped me gained so much knowledge/confidence to fix almost any bike!!!!
Salute and Blessings!
Helpful demonstration and kind of funny but still focused.
Interestingly when I first worked on my bike, I thought I had a Cassette when really I had a Freewheel. So making sure you pay attention to the tool fittings and get the right tool the first time makes a huge difference. Thankfully since I’m upgrading from a Freewheel to Cassette I now have the right 🛠 🧰for the right component. It makes a difference.
where can i get a video-guy to test this ?
And such a chary one will be hard to find....
Just discovered this channel, VERY grateful!
Thank you Calvin and Video Guy!
the video guy demo was just awesome and the simplest way to understand why cassette are used in modern cycles instead of freewheel :)
Love a bit of tech Tuesday!
Very good explanation. Thanks
Another fantastic lesson from Calvin! Today’s lesson reminds me of my high school physics teacher. In 1981, lol. Thank you!
Straight to the point
finally a understandable video on this topic.
Good information clears all the confusion.
Still another excellent and informative video from Calvin and Park Tool
Excelent explanation, now where i can buy some Video Guy hubs for my bike?
This channel has helped me a lot with my bike.
Bro.. I like your video. Simple but very clear explanation. 😍😍
Calvin Jones and this vid are amazing
You are a great teacher! Thank you Sir 🫡
Calvin is the best
Yeah, my bike has a freewheel. Once I ordered a replacement cassette, and I instantly realized I got the wrong thing and actually needed a freewheel. But my bike doesn't seem so inexpensive: it cost hundreds of dollars.
When there was still a bike shop around here, the guy made all sorts of suggestions about how to avoid the axle breaking so much. He never mentioned that getting a cassette system might help.
I've purchased a $600 SE Bike, and it uses a freewheel as well instead of a cassette. I found that bikes usually only have cassettes pre-built into them if they're almost $1,000, or if you find a bike that specifically has one. In that case, the other components would probably be compromised as lower quality in turn for the cassette.
Thanks Calvin! I always mess up these terms!
Nice work Video Guy!
Calvin is a cool dude.
Great video 👏👏👏
I love Tech Tuesday
no bs straight to the point.. loved it
Just an awesome channel with amazing explanation
Great video!!! thanks!!
Very informative. Thanks.
thank you.. this is helpful..
1:45 - if I see correctly that's a 10-speed freewheel? Where did you get that thing? I thought most freewheels were gone along with 7-speed drivetrain, 8-speed being a real rarity.
Yes, there are 10 speed freewheels. It makes the right side of the hub axle quite long, making the axle system even weaker. However, they are made. Sunrace is one such supplier.
Hi Calvin , I bought an electric bike and it has a 7 speed cassette on it with 7 individual cogs that slide onto the hub and it came loose, so I took it apart and needed to contact them to get the correct lock ring tools, they have the idea and call it a fly wheel ? I said you mean freewheel ? The technicians, if you can call them that, sent a video of them removing the lock ring with a hammer and screwdriver, I said that's a bad idea and need the correct tool, but they don't have that tool in the assembly factory ,can you believe that ?
cool looking video guy
Ever seen a freewheel freehub its a freewheel with a hub and cassette all sprockets are separate with spacers in-between
And the bearing is on the end of the hub
Amazing... thank you Calvin👌🏼👌🏼👌🏼
Turn up at bike shop- “My gears are a bit funny”
Bike shop- “You’ll need a new wide legged video guy fitted”
Thank 😊 🙏
Excellent v6😮
What happens when the ball bearings system inside the freehub break? Is it possible to just replace the freehub or does the whole axle need to be replaced? Or do we need to replace the whole wheel with the rims and the spokes?
Bearings will be in the freewheel so if the bearings are shot then it’s a straight forward freewheel replacement
Well explained
So good ….!!
Do the 2 basically operate the same way just with different tools for assembly? I just bought a new rear wheel with freewheel or cassette. I chose the freewheel, would I have to return the wheel if I picked the wrong one? I appreciate the help, ty.
They work differently than each other. A freewheel contains a one way clutch and the unit then threads onto the wheel. A cassette is just a set of sprockets that are then splined onto a freehub body that has a one way clutch in it/the hub. Different tools and different designs.
@@parktool Hi Truman and Calvin.
I understood this question differently, so my answer would be different:
They both have sprockets aka cogs for the chain and a ratchet mechanism. The difference is the placement of the ratchet mechanism. In a freewheel, it is attached to the cogs as a unit. In a cassette system, it is attached to the wheel as a unit.
Apart from the bearing separation benifit, the cassette system is cheaper for the manufacturer, since the ratchet mech is not replaced as often. One hopes (ahem) that this saving is passed on to the consumer ...
Just this week I had a customer with a bent axle. You guessed: it had a freewheel.
Used to break axles often before I used cassettes
You don't tell us if we can separate the cogs from the freewheel. A tool for the ring with the outside fittings, as the cogs are fine but me freewheeel is a little tight
Thank you! 🚴♂️
The power to confuse 😂
Man I wish I would’ve found this before trying to take off a lock ring that didn’t exist with a lock ring remover and a chain whip.
Are all free wheels the same. Will a generic free wheel fit a Campagnolo hub...?
Freewheels are not all the same. Most all freewheel use a "BSA" or English threading for compatible hub. Campagnolo is an old company and did make hubs accepting a freewheel. The hub has a large thread machined into the body. Freewheels will vary in number of sprockets and width. No freewheel will mount a hub designed for a cassette, such as the modern Campagnolo hubs.
What's the weight difference? Also cassettes won't wobble like free wheels because it's because of untrue threading that causes freewheel wobble.
The freewheel hub + the cogs would be heavy since i think they still made of steel
yes
Your shifter will not allow you to run an 11 speed cassette.
Do you sell videos guys? My lbs is out of stock.
What when ratchet is broken i casette, you need to change entire wheel?
Some brands have the freehub (ratchet system) as a replaceable part. But some brands you must replace the entire hub or whee.
what do we do when my 11 speed can't reach at 11 speed and it can reach only 9 speed
it could be a couple things but im guessing it is either the low limit screw is too tight and is limiting the derailleur to the 9th cog. Or it could be your cable is too loose. In that case you should shift into the most difficult gear and try to release a few more clicks out of the derailleur then loosen the cable pull it tight and refasten it. Check out our video on how to adjust a rear derailleur.

one of the cogs on my freewheel is broken is it possible to fix it?
At that point it is best to replace.
Hi. I have a freewheel onto my 20" folding bike. Recently, I'm annoyed by spokes breaking at the J bend on the drive end. Can you tell what might be wrong? I take her on long distance tours on tarmac. However, the roads are not always in good shape.
I weigh 75 kgs and my rear rack carries around 7 kgs of cargo while the front weighs around 3kgs. The wheel is single walled steel with 28 spokes.
Would changing from freewheel to cassette be better? (That is if I ever could?)
The common cause of broken spokes is typically low tension. Spokes see a stress cycle by slackening each revolution. A tighter wheel see less of this tight-loose effect. But all wheel with time will see fatigue spokes.
At this time you likely need a rebuild. A cassette hub will not change this issue of stress on the spokes. However another cause is simply cheap and poorly made spokes. Have the wheel rebuilt using good quality stainless spokes, and get them tight.
@@parktool Ok. I'll have a word with my LBS. Thanks.😀
@@parktool very informative. I love it
dont think the bearing looks further out in the cassette from the example shown,... !!
Hello is a useful video for hank you I have a schwin taff mtb and would like to up grade from 3-8 to 1-11 I am not sure if the rear hub is free wheel can you help me to know about that thank you
8 speed are usually cassette hubs, but you can't fit 11 speed onto a 8/9 speed hubs
I keep breaking axles and I really need to change from a freewheel to a cassette.
Can you convert Freewheel to Cassette?
Unfortunately you cannot. A new hub will be needed and typically a new wheel makes the most sense at that point.
Cassette vs freecoaster?
i have a lock ring with slots on the outside . remove this lock ring , all sprockets come off individually ,with 3.2 mm spacers in between {except the smallest of the 7 cogs ,14 tooth has a built in spacer ] . inside the hub is splines that do not turn backwards with the hub . there is no hollow bolt to secure it . the hub has 2 different diameters .it steps up on the inside to hold the larger cogs . there is a wide spot on the hub cog splines so that the cogs can only go on one way . is this a hybrid freewheel of some type ? or a freehub . i have not located a tool to remove the hub yet . so im not sure what i have .
Very like that is a freewheel, not a cassette. See the bottom of www.parktool.com/blog/repair-help/freewheel-removal-and-installation
That lock ring holds the cogs on to the ratcheting body, which is threaded to the hub. Also likely it is a FR-1.3. See ua-cam.com/video/iTJ3taJHOn8/v-deo.html
@@parktool thank you .. I think your correct.
But is it the only reason?
It makes changing sprockets much easier.
This guy could be Frank Zappa's brother.
What brand is that disc
That is a Tektro disc.
or is there an effect from the cassette because it's too big
You can buy different sizes of cassettes, the large cassette was an example.
or the cassette is too big it will bunk in the cassette when we full shifting
Video guy :D
my question is what do we do when we can't reach at 11 speed only at 9 speed
Could you rephrase your question?
As long as we're getting our terminology straight let's talk cogs vs sprockets.
why is my 11 speed cassette wont reach at 11 speed only 9 speed can reach
These videos may help: ua-cam.com/video/B37TW_YVC8E/v-deo.html
Ithink your rear derailluer is just for 9 speed. Or your shifter too.
or it just my shifter because my shifter is deore and it is 10 speed
Is your shifter a 10 speed?
How to grow mustache like that
😂
Nothing hard to understand about that
good video, but you spread your video guys feet way to far lol. none the less your videos have helped me get the right tools many times over the years, specially since all the bike shops a disappearing and they charge too much anyways
👍🖐🇹🇷.
