Very happy with product K M C. 9 speed. X9
This was the recommended chain for my Fiido C21 Pro bike. Changed the chain after 6,000 miles. Was extremely happy with the result. Smoother peddling and very precise gear changes.Cut the old chain off with angle grinder because I didn’t have missing link remover tool. Followed instructions supplied to click the new missing link into place using pressure on the crank. Audible click.

Decent chain
Came well oiled. I’ve had no issues with it at the moment. Only problem is quick link is not so quick to install.
User
Just what you'd expect, no problems at all.
Perfect, no complaints with this. You'll need a chain tool, but then fitting is easy.

Good 9 speed chain.
Always use these on my Electic mountain bike.It eas the chain the manufacturer fitted and although it hets changed every 18 to 24 months along with a new cassett it gives good service.

The best bike chain I have used!
Replaced a Shimano branded chain on my road bike, and is so much better! Very rust-resistant throughout a cold, damp Scottish winter. Looks as good as new even after a few months with minimal maintenance, just an occasional clean and lube!
User
Good chain

Buona anche per E-MTB,
Ho una E-MTB abbastanza potente e temevo che la catena non reggesse. Sono contento di vedere che nonostante usa la bici per Trail/Enduro, la catena non da problemi.

Not for e-Bikes!
Not for e-Bikes!My CUBE Touring Hybrid came original with the KMC X9. It has a 75 Nm motor and I ride fairly mixed, but mostly longer distance. The chain is never under any harsh conditions and I avoid riding it in rain. My first X9 chain lasted roughly 600 km, but I figured hey - it might just be a poor example. So after this first X9 chain, I tried a Shimano e-Bike chain indtead. That chain lasted 1200 km, surprisingly. When it was time to change again, I thought why not buy the original chain and give it a another try?It soon became clear that it was a mistake. A really, really poor mistake. The chain started skipping after just 150 km and skips at least twice while I ride. I only expect it to become worse. The rollers on the chain have already begun to show wear and at the time of writing this, I've only ridden 300 km with this new X9 chain. It's closing in in 0.5% wear and I don't think I'll reach 500 km until it's time to change again.I cannot recommend KMC X9 to anyone who rides an e-Bike, even if it came original. I am not buying KMC again.
