What is the expected lifespan for Campag Sprockets?

Question

I cycle 150 to 200 miles per week and have worn out campag sprockets in 6 months

campag sprockets are known as gears they were on new bike bought in April and worn out by September

new SRams chain did not make any difference to slipping when under pressure

Answer 1

It can only be a few things. Chain, cogset, Derailleur, or freehub.
You have a new chain and the cogset should last for years and years, sand or no sand.
I would check two things and one might ne painfully obvious.
If the slipping happens only on certain gears, I'd adjust the derailleur perfectly. Some bikes can be a pain to get just right and if you have a hard time make sure the wheel is centered and that the hanger is not bent.
Secondly, if you have an extra wheel I'd try the cogset on the other wheel. if it still doesn't replicate the problem I'd say it is the freehub and take it to your local bike shop for a rebuild.
Good luck.

Answer 2

I'm going to assume your talking about Campagnolo Components, and as someone said there are alot of variables involved and the most important variable is how well you maintain your drive-train.

If your riding 150 to 200 miles per week the components need to be lubed every hundred miles and removed and cleaned and lubed every two hundred miles regularly.

You said the new Sram chain did not make any difference to slipping when under pressure. Just a bit of information so you know, never replace a chain without changing all your gears, the old gears and new chain won't mesh together and will cause your slip-age, it's not a good idea.

If your thinking of changing to Sram or Shimano for more life expectancy don't bother because you'll gain nothing, the only way you may see any gain is if you move to the high end stuff like Campy Records or Dura Ace, and thats high dollor stuff, but again it's all in how well you clean and maintain your equipment.

Well maintained equipment should last for years.

Answer 3

You sound like a masher. Perhaps you should seek advice on smooth gear shifting and self maintenance on your machine.
You can get years of use out of a drive train if it's used properly and kept tuned and cleaned.
Your mileage is not excessive and should not be a factor. There must either be something wrong, or you're doing something wrong.
Also, get a second opinion on the wear on these parts. Some bike shops can be less than scrupulous to an unsuspecting customer.

Answer 4

Ric is right. What it sounds like you did was to let the chain get stretched too much and then replace it without replacing the cassette. The teeth on the cogs have worn to fit the old chain and don't mesh properly with the new chain. On the chain, from pin center to pin center, it is 12 inches. At 12 and a sixteenth, you need to replace the chain and the cassette will be ok. At 12 and an eighth, the chain has stretched too much & the cassette has worn to fit it; both chain and cassette need replacing.

Answer 5

????????what the hell are you riding through sand? If you wore them out in 6 months something is hugely wrong if your gears are slipping i think you might have mistaken a badly stretched chain for worn out cogs if that's the case and the cog set is only 6 months old throw a new chain on (preferably a high quality one) and clean it regularly...I have never in all my years in the industry seen anyone wear out a cog set in six months something don't sound right

Answer 6

You haven't mentioned wether they were new or on a second hand bike, are the cogs worn, has the bearing collapsed? If they are new take them back. Distance cycled makes no difference, they should carry a 12mth guarantee. You will need the receipt though.

Answer 7

there is a lot involved with this question. sand, dirt lube, and the condition of the chain play a big roll in the life of any machine

Answer 8

and what is a campag sprocket?
