I want to check my derailleur chain with a KMC Regular Chainchecker. Do I need to replace my chain when the Chainchecker drops in between 8 links?

In case you regularly checked your chain and the Chainchecker now starts to falls through, it indicates that your chain has worn for 75%.

In principle the chain can be used for another 25% of the distance already covered. (E.G. the mileage is 3000, and the chanchecker starts to fall through, then replace WITHIN the coming 1000 miles)

We recommend you to replace the chain within this distance, in this way you stand a good chance not having to change your cassette and chainwheels.

I have bought your X-series chain. After unpacking, I found that the chain is rather sticky on the outside. Is that normal?

During manufacturing one of the processes involves lubrication, we inject special grease into the chain. Right now a part of that grease stays on the chain's outside, which is needed to conserve and protect the chain during storage.
KMC recommends you to take away the excess grease from the chain's outside by spraying some (eco) cleaner along the chain and immediately wiping it. By removing the grease outside you will prevent it from atracting too much dirt. Make sure the grease inside the chain is not affected!
Beware of keeping it a little oiled after every ride in order to prevent rust.

Hello! I just bought a new KMC X9L chain. But it is too long. What to do?

The chain you have bought has a standard length (116 including MissingLink), long enough to fit most bikes.

Take off the old chain, and count the links
Count the same number of links on the new chain
Take a chain tool, and press the pin out on the correct length and do make sure the chain ends on the inner-link, for re-connecting by MissingLink

Hi, I have a question concerning the Missing Link. Do I have to change the Link everytime I change the chain (always a new link for a new chain)?

If the MissingLink is a 'Re-Usable' type you can use it as long as you ride the chain, once the chain is worn down, you need to discard of the MissingLink too.
If the MissingLink you are using is a 'Non-Re-Usable' type (MissingLink-1 and MissingLink-10 PRO), we advise you to change the link every time you open it.
We reccomend to keep one spare set with you during riding.
