How long would you guys expect a cassette to last, assuming that its well maintained, regularly cleaned paired with chain that is also cleaned and lubed weekly, and not left to stretch too far?

Keep it clean and oiled, paired with the same chain and using all the available sprockets it should last a long time, 10,000 miles.

At least 4-5k IME on a road bike.

So would you say that this:

That's not worn though, it's actually broken! Got to be a warranty job, no?

Eh? What's going on there? Is there a cog/gear (!!!) missing towards the bottom?

Not normal wear and tear that, just broken.

I can't see the picture whilst at work - but a quick question how mechanically sympathetic a rider are you? Do you change gear under full load or just hammer the shifters till it changes? I’m not saying it’s acceptable to fail due to unsympathetic usage but it may be a contributing factor and something to modify in your riding to prolong the life of the replacement.

You are Chris Hoy AICMFP wink

But in all seriousness that has sheared right off and should be replaced under warranty if it's not too old, take it back to the retailer in the first instance

Luck of the draw, I would say circa a year of av-heavy riding, I usually change to match the chain

I had to change mine a few weeks back , as one of the rings had cracked, didnt really notice tbh, the LBS were quite surprised

Otherwise they said that and the chain were half worn after 4/5k miles, but cleaned every week

Answering the original question, the chain wears much faster than the sprockets, so I use three new chains with each new cassette and swap them every 1000 miles, re-using the first chain after 3000 miles, and so on.

Should be able to get 10,000 miles from a cassette, though I use 8- or 9-speed and not 10/11, as the sprockets and chains are narrower and seem to wear out faster...

I've never managed to break a 7, 8 or 9-speed sprocket...

Has it sheared or has the retaining nut just worked loose? I can't see the pic very clearly at the mo.

Rolls, Jimbo, gazza, Winston, yes, a gear/sprocket/cog has sheared clean off, the cassette is now slightly loose and wobbly.

Engineer, i appreciate where your coming from, but no, i'm nice to my bike. It makes me cringe when i read EPS/Di2 reviews claiming they tested shifting under full power.

itsnotarace, that may not be so easy, its a Canyon, so no shop to take it back to. Having said that, i bought it in march, within 100 miles a link in the chain splayed and fell to pieces, Canyon were brilliant and a chain was at my front door within 48 hours, not sure how they'll be with this though.

Melon, isnt that what a warrant should cover, the odd bit of bad luck that is when you receive the faulty product, not the next person that bought one? The drivetrain is 6 months old, with about 1300 miles on it, and 100 less on the chain. Not quite the 4/5k use youve had, with that many miles i'd just replace it myself, at my current rate thats 3 years use.


Nice that the majority agree its a faulty product and needs replacing under warranty, unfortunately ive not had time to ring Canyon today, and theyre shut weekends, and i really wouldnt be surprised if they tell me its had its fair use and to get on with it. Perhaps i'll try Campagnolo from the off.

I've got a few friends with Canyons now, one of them had a problem with his Mavics. Canyon advised him to take the bike to his nearest Mavic dealer and get a repair done, they re-reimbursed him for the cost. Relatively painless.

Yours is deffo a manufacturing defect so they may well just ship you a replacement cassette

Canyon - grrrrr !!!!!!!

I had a Dura-ace shifter fail
On their asking I removed it and shipped it back to them
It was replaced without question

The bad news was they offered 20 quid for my LBS to fit it, fit new bar tape and replace the Dura-ace cable which had jammed when it failed

The Dura-ace cable alone was 20 quid from CRC

Fill in the gaps yourself

Great bikes, superb prices but budget a bit extra for warranty work

15 minute job to fit it yourself. The cable is less than £4 from any LBS, you only needed new inner
