This is not the same chain as many of the (not so positive) reviews have rated it. This chain used to be the old Z9000 series, but was updated into the 9.93 chain. The biggest difference is the sideplates have been redesigned and are now zinc coated. The inner plates also have a new coating than the previous version. And finally, the pins are new. Oh, and it now comes with a removable missing link, for easy removal for cleaning.

That said, here's the pros and cons: Is it the lightest chain available? Absolutely not. Is it compatible with Shimano and SRAM 9spd? Yes it is. Does it last? In my experience, it lasts every bit as good as the low-end version from the two big S brands (Shimano HG-93 and SRAM 951). While I admire the Shimano chains for their excellent shifting and low tendency to break, they stretch faster than any of the others. Stretching is the #1 cause of drivetrain wear, because as the links get longer, the chain 'rides up' on the sprocket teeth and wear them thinner.

The price point is there with this chain. You could buy two for an equivalent premium model chain from the big S brands and change them out quicker. Meaning, not only will you get more life than having bought one premium chain, but by installing the second chain halfway through, you'll cause far less wear to your drivetrain.

PROS: Cheap, Compatible, Easy to Use

CONS: Heavy

BEST USES: Sprinting, Avid Cycling, Casual Riding, Commuting

I needed a new chain, and this one worked. It's actually been through a bit of hell, with a bent rear derailleur and a snapped hanger at one point that lead to some sketchy shifting and tension. I fixed all that, and tested the chain out, and it's still as good as new, and working very well. I've got no complaints.

PROS: Affordable, Smooth, Chain

BEST USES: XC, Trail

Based on my experience, I will not be buying another KMC chain. It shifts okay and thankfully hasn't broken, but is wearing too quickly. I'll probably buy another Shimano chain.

As the JensonUSA description says this chain does put the "S" brands to shame. This chain works really well, best chain i've ever used. My friend and I both got new chains and I got this chain and he got a Shimano XT chain and right after putting it on his bike and riding it broke for no reason, he ended up getting this chain.

Product was easy to work with

PROS: Lightweight, Easy to Use, Compatible

BEST USES: Climbing, Casual Riding

excellent delivery and packaging

PROS: Durable, Lightweight, Easy to Use, Compatible

This chain has lasted for over 1 year without any problems. I ride an average of about 4 miles a day riding back and forth to work, so I've put this chain through its paces between riding to work and the occasional race or friendly trail ride.

Kmc has become my favorite chain. These chains wear out sliver than the shimano and sram. Missing link connector makes this the easiest chain to install also. You can not go wrong buying a kmc chain!!

PROS: Durable, Compatible, Easy to Use

I bought this to use on a 2x7 setup with 9 speed chain rings. The 8 speed chain rubbed the large ring a bit in certain gear combinations, and the 9 speed chain solved the issue. It shifts very smooth, and the KMC missing ling is great.

Comes with a re-usable link - good. Inexpensive - good. Sets up and runs smoothly straight out of the box - no kinks or stiff links. Snapped my rear derailleur on my third ride with a new drivetrain, but the chain is unaffected.
Three thumbs up.

Works great, strong and reliable. If your running 9-speed not much need to get anything else.

Chain works great so far. I have only had it for 100 miles and it hasn't broken yet. I noticed that my cassette tool has the same chain on it. If a tool manufacturer uses this chain on its tool it must be good.

Durable, good finish, and equal or better than Shimano or SRAM. Nice to have a quick link too.

I use these on the dh and the f/s trail bike.

CONS: Heavy

Good delivery time.

PROS: Strong chain, Narrow Shimano compatible

CONS: It ain't shiny in mud

Works well so far. I will never buy a chain without a quick link.

Awesome as always

PROS: Easy to Use, Compatible

BEST USES: Commuting, Casual Riding

Great chain that lasts a long time for a great price. Not sure why you’d spend more for other brands.

While I appreciate full-suspension bikes are particularly hard on chains, I expect more than 4 rides out of a new chain before it breaks, which is what happened with this chain. I've broken chains while racing before, but never this new. To make matters worse, it flung off the chainring into the leaf litter beside the trail never to be seen again. Race over, time to walk out of the woods. I know this wasn't the chain's fault, but I had to vent!

Honestly, there are so many factors that go into how a chain performs, it's hard to compare. I bought two of these because they were so cheap, figured I'd swap them every few hundred miles and get even wear. I've been riding one for just a few rides, on a new xt cassette. Today it started making a blip as it went around. In the past this was a precurser to a break, so I got off and inspected it. Has anyone seen this happen to a chain? One of the rollers just disappeared. Must have been some brittle heat treatment for it to just break in half. Not going to bother with warranty, too much hassle for a cheap disposable item. Good thing I bought two! Next time I may spring for a more expensive chain, although I've had good luck with KMC.

Simply put, terrible. Broke it on the first ride. May have been a manufacturing defect or something but regardless, first ride.

The chain broke within the first hour of use. Fortunately I wasn't climbing a hill. Online reviews for this product are horrible. Consumer Products Safety Commission should look into this product. Jenson shouldn't sell it.

Chain broke within first hour of use while just biking down the road. Worst Chain Ever... If your new bike has one, replace it now and save yourself a ton of trouble.

This chain WILL BREAK! There is no doubt about it! I Bought a brand new $1000 bike and it had this chain on it. The 3rd time of riding it, I was simply accelerating for a jump, and it broke! Think of your shins!!!

I ride variouos bikes, have always used Shimano CN7701/XTR chains and they've lasted well and taken abuse. My current bike's small ring is about done and if not careful shifting down to it you can get some chain suck, have had this happen numerous times (mostly muddy) with my CN7701 chain and no problems, never bent or twisted. Bought this chain because I had read fairly positive reviews about it and it was 1/2 the price, so I thought I'd give it a go.

Well inevtabaly I got chain suck, I was riding to meet a group in the early hours, it was dark, I removed the quick link and put the chain back on, couldn't use any gear, thought "Darn rings are worse than I thought" so rode the entire ride in my 38t ring and 32 outback, never thought to check the chain for a twist until I tried it on another bike and that gave trouble also, then I looked and found the twisted link. Cannot believe how easily this chain twisted, honestly not worth it even if it was free.

CONS: Weak, Very Weak
