Cassette wear(11 posts)

Cassette wearHiggins

I have just replaced the chain on my Campagnolo 10 speed setup. The shop thought I might have left it too long to replace the chain and said there could be problems with the chain jumping. Well, they were right. On my 'favourite' cogs the chain is slipping and jumping when under pressure. I found this out on a little 12 mile test ride. For most of the ride I used the cogs that I don't use very often to avoid the slipping. Obviously I need to replace the cassette. My question is, have I damaged my new chain by taking this short test ride? Or am I being paranoid?
No, but try not to put too many miles on, with theMR_GRUMPY

old cassette. Just get a cheap(er) Daytona 10 speed cassette.
Just buy the worn cogs. nmSpunout

So what about the chainrings in all of this? Should I be replacing those too?
Probably not, unless it skips in front.MR_GRUMPY

Buy the Campy Chorus steel cassette; they will long outlast the Ti versions. How many miles before you had to replace the chain?

Well, I think I left it too long and I have probably done about 3,000 miles. The shop said I should change it every 1,500. All of this really confuses me - when to change cassette, when to change chain etc etc...
Something's wrong here!Kerry Irons

If you keep your Campy chain properly cleaned and lubed, you should be able to get much more mileage than this. While I ride mostly on flat roads, I do weigh 180 lb. and I regularly get 10K miles out of a Record 9 chain and steel Chorus cassette.

Of course, the bike shop will tell you 1500 miles, but they are selling chains and cassettes to pay their rent. If you keep the chain and cassette clean (and I clean mine every few hundred miles) you should have no problem getting 3000 miles on a chain. Maybe there was some adjustment issue causing the chain to wear excessively. I have over 1000 miles on a campy 10 speed chain with hardly any evidence of wear. I plan to change it no soooner than 2500 miles at this pace.
3,000 miles is time, IMHO for a new chain. Cost-wise,Spunout

it is the best thing to do. Also, performance and safety will be enhanced.

You can try to push 5,000 miles out of it, but then you are looking at new cogs or rings...but it isn't worth a $50 chain at 3,000.

While all theses replies are valid - and I do change chains every 4000km (2500 miles), if your new chain skips on a few cogs don't panic! If you just keep riding, the new chain will mesh with the old cassette after a few hundred miles and you wont notice a problem - buy a new cassette and chain after another 5000 miles because then they both (chain and cassette) will be toast so you might as well get every last bit out of them. I don't know why its not common knowledge that a new chain will mesh with a worn cassette nerertheless its true. Front chainrings will be fine on that mileage.
