Product Customer Reviews

I was skeptical of the quaiity as it was so cheap and expected it to break. But pleasantly surprised. This works great!
Put it on a winter bike that gets lots of abuse. Didn't wear out any faster than any other chain I have used.
Like most of my purchases from Decathlon this cassette was a replacement for my existing one that needed replacing
After umpteen thousands of miles ,chains do wear out and this was a replacement for a similar chain that lasted for ages
Works well. Great speed link.
It's a KMC chain boxed up in a Decathlon box. From what I can tell, it's a KMC X9 Grey chain. Cheaper than buying it in a KMC box. It's been on my bike now for a couple of months and I'm still happy with it.
I damaged the chain and needed 6 pairs of hands to join the chain. Pin wouldn’t push through and damaged the chain do have to go back and buy another chain and separate split link. So not impressed at all.
Did the job, no quick link though so a little dissapointed
I've been using these chains for many years and cannot fault them
Within one month of use the chain frequently slips on elevation.
Hello Vishal,
Thank you for letting us know about the issue you faced. We would be happy to help you with this. It is unfortunate that the chain is frequently slipping. I apologize for the inconvenience that has been caused.
I suggest you reach out to the nearest decathlon store and our workshop technician will be able to identify the issue and provide you with a solution.

Installed the chain and rode for hardly 2000 km. The chain started to loosen very fast than expected.
Hello Kush,
Thank you for your review. The cycle chain is a component that is subjected to a lot of wear and tear. The maintenance of the drive train will play an important role in how long components can last. There are also external conditions that affect the performance of the drive train such as rain, dust, etc. The impact of all the above-mentioned factors makes a difference in the number of Kms that you can churn out of a chain or a cassette. I will keep the product manager informed of your feedback and thanks again for sharing. Feel free to reach out to me if you have any questions.

A chain is a chain is a chain, normal quality, normal behaviour, don’t know why this costly.
Chain was shimano so it's good and I had issue with its chain link it was bent while I purchase the cycle, so I replaced it with new one and it provide easy movement with less noise and less friction its a good quality one...
After fitment I did 300BRM, chain set supported well.
Blindly go for it
