KMC Z8.1 8 speed inner chamfering 7.1MM pin length Bicycle Chain (1/2" x 3/32") Gray 1 pcs /Steel 116 links

I have 3x7 setup on my mountain bike And I had to remove 4 links, however, this was pretty easy to install and so far it's been riding like a charm. A comes pre lubricated when you get it out of the Box and so it's not necessary to add any to it unless you feel like removing the factory oil and then adding your own by bike lubricant. I will add that if you do not take off the lubricant and your cassettes are dirty then expect your shin or save your cap to have a lotta black deposit because of the viscosity of the oil and the grime on your cassettes. Otherwise the bike chain works perfectly.Will update if I see any accelerated degradation

Excellent Bike chain, totally worked for my bike. The first one I bought I made couple of mistakes so I ended up buying another one and that worked out. While it is not advised when cutting a chain to reuse the riveting pins that are already on the chain. I have reused the rivets and have had no problems at all. What I do is before reinstalling another part of the chain, I put a drop of oil on the chain rivet, clean up the excess, then using a chain tool I carefully replace and push the rivet back in place making sure the rivet makes contact. Then after the rivet is in place I give the chain a slight bend and then I check that it's rolling like all the others. If there's any advice I will give to others buy chain rivets when reconnecting a chain, never reuse the rivets already on the chain unless you have to, but like I said I have had no problems with the method I used. But I agree with the manufacturer and other mechanics that it would be wise that you replace the chain or just make sure you buy new connecting rivets that work for your chain when reconnecting links.One thing I have learned is that when installing and threading a chain into the rear derailleur is when pulling the derailleur down put the chain over the top pulley wheel then under the bottom pulley wheel. What I love about this chain is the master link or quick link that comes with. They connect easily and it's even easier if you have master link pilers I used Park Tool MLP 1.2 Tool. That makes the job so much easier and faster than using needle nose pliers or your hands. Chain installment can be confusing, usually it can be guess work. KMC unlike some manufacturers actually tells you the narrowness of the chain on the packaging. Also if your using products from the same manufacturer like Shimano that manufacturer will tell you to use only Shimano products, well you can but it's also possible to Mix and match products. I highly recommend this chain, it's easy to use and install and very affordable.Highly recommended!

For the price I got my moneys worth in a year, but it kept going. I rode at least 10 hours a week on gravel, dirt, mud and basketball sized rocks and it was perfect. Then I had a bad year, didn't ride, stored it without oiling it and found it rusted in the garage which was my fault. No telling how long it might have gone with better care.

I put a fair number of miles on my bike and typically change them at 3K miles so as not to wear out the other components. I don't want to spend too much for a chain and these KMC's seem to last as long as more expensive brands.

Installed on a hybrid bike with a seven speed cassette. The old chain was so worn that it wore out some of the sprockets on the cassette. New chain and worn out sprockets do not work. I had to replace the cassette also. Oh well, live and learn.

First new chain I've installed so I had no idea if it would work or what I was doing. The key thing to pay attention to is 3/32 vs. 1/8in side plates. I was able to confirm that my original equipment chain was 1/2in x 3/32in links. Next problem was trying to figure out how long of a chain. So I focused on getting a chain overly long with the 1/2 x 3/32 links and the Oumers Universal Chain tool. Bottom line is that this chain is working fine so far after I cut it to length and used the included closure link. Park Tool has a great video on how to size the chain and there are videos about how to install the closure link without a tool.

KMC makes very durable and long-lasting chains. I have put tens of thousands of miles on them and never had one break while cycling. These chains do stretch and wear over time, but with proper care they will function well for 2000-3000 miles. Amazon has great prices on KMC chains, so I keep a few in my parts inventory at all times.

Just your typical bike chain. I had no issues with it and it lasts a reasonable amount of time (15k miles give or take).
