KMC Bike Chain Z7, High Performance Bicycle Chain, Quality & Highly Compatible with Chamfered Inner Plates, Shifting Performance Bicycle Chain, Multi-Speed Bike Chain, 1/2" X 3/32" - 114 Links

Chain was easy to install on my son's 24" 21 speed bike.

Left 5 stars as it appears to be a quality chain. It's the same type of chain that came with my e-bike, and I wanted to replace it while replacing a rear tire. Ordered it because it was the same brand and type and said it was compatible with all 7-speed drive trains. My ebike is a 7 speed, so thought I was ok.I removed my rear tire, but found the factory chain had no quick release link, so had to buy a chain break tool to press out a pin to remove old chain.I hung the chain, sprayed it down with brake cleaner, wiped the factory oil off and let it dry, then soaked it in chain lube and hung to let that dry. It was all set. I had a big problem with figuring out which way the washers went on on my rear axle which took days and a lot of struggle to get right, but finally I got it together.At last I could put the new chain on and get back to riding.But I was destroyed when I threaded the new chain on, only to find that it was several inches too short!I laid out the old chain next to the new and found that this chain is about 6 inches too short. Some research at my bike manufactuers showed that their chain must be custom, as it's 130 links, where this is only 114. UGH!And a search of the KMC website and all their chains showed that they don't offer a 130 link model.Debating whether to order an expensive 126 link chain from them, or the replacement chain from the manufacturer. After a week with my bike apart, I'm afraid they'll be shipping it from China and it might take weeks.Moral: Be sure to check the link count. This is NOT compatible with ALL 7 speed drive trains.

really good product, it is perfect for my replacement.

The chain is ok. But the problem is that the manufacturer's packaging is fragile - the plastic box easily cracks, so one or two links fall out through those cracks. Thus getting the full set is just a matter of luck.The first chain I bought didn't have one of the links due to that problem. The second chain also had the box cracked, but luckily both links were still there. YMMV.

Good value

This chain was easy to install and strong. Been using it for months now with zero issue.

KMC chains are great never had an issue with him. Our the price keeps rising like everything else. I think Amazon can do a little better in pricing. They should also look at bulk pricing for some of their customers.

KMC chains are my go to brand.
