Cassette Wear

[Like-A-Boss]

Here you go guys...a cassette wear checker: http://www.biketoolsetc.com/index.cgi?id=676176439428&d=single&c=Tools&sc=Cassettes-and-Freewheels&tc=Cog-Wear-Gauges&item_id=RO-CK

 

I'll sit back and read Johan's response to this tool

Just found it too. At $22 I would get one if it works.

Even at our great exchange rate, it's a cheap tool to add to your tool box.

 

I recon it should work - if you look at it, it really just simulates a chain on the cassette, and you add the force...IMO...of course

...but then what happens when the chain on the tool is worn out?

What the heck, just go and put your bike in your favourite (most worn) gear and go for a short high-powered ride. If it doesn't slip, it's fine. Who needs a tool to simulate that?

 

Further, it does not exactly simulate a rear sprocket and jockey system and I have my doubts about this tool. A driven sprocket has the chain entering without tension and chain exiting in tension. This tool allows you to artificially wrap the chain and get a false OK reading. 

 

Don't bother.

Boring technical person here....

You chain wear is couple to your mileage. I change my MTB chains every 1000kms' date=' not matter. If you a heavy guy, climbing alot your chain will stretch quicker. I am 70 kg, and some of my chains are up to half a link longer after 1000kms. Cassette wear, is a given.. just swop it when the new chain does not fit the old cogs.

I want to see you STRETCH a chain, especially half a link! A chain does not stretch, the metal inbetween the links wear out, giving more play and so the chain appears longer, this has factors like cadence, weather and lube. A cluster is usually worn out when a new chain skip\jumps when you pedal hard, if it hapens when you pedal shoft, its long overdue.

 

 

Dirtbreath' date=' you should know better. Throw away that stupid tool of yours, it really isn't not your style. (I listened to Spanish Train earlier today).

 

The reason you're getting different readings on different links is exactly why that tool is rubbish. It measures the dirt inside the rollers. You want to measure the sideplates, which are not variable thanks to dirt.

 

JA-Q001 will be my spokesperson from now on, provided he finds a nickname that's easier to type. He's right.

 

Kenny G-spot is off course. Changing your chain each X miles may be a waste, may be overdue. You'll never know.

 

Measure your chain regularly. When it reaches 12 inches and 1/16th, then it is 1% elongated and should be replaced. If it is 2% elongated, your cassette is ruined. Keep on swapping the chain until it starts to skip as my luitenant pointed out.

CUT....CUT.... CUT....and snip

 

What will measuring a chain help if it does not stretch?

 

JB I think you and you spokes person need to get you stories straight before posting

I do not think you have quite grasped the concept of chain wear here.

 

When a chain wears it does get "longer" but does not stretch.

 

Oh, I'm not a spokes person as I prefer nipples.
