Strengths:    The coating allows it to stay much cleaner than XT chains I think.
Quite rust resistant.
Strong since I've used them. I've never had one break on me even with my style of mashing on the pedals instead of pedaling lightly and shifting under load on my DH bike.
Pins they supply make it super easy to install the chain. You never get a stiff link.
Shifts very well.
Good value.


Weaknesses:    None that I've found yet.

Bottom Line:   
Great product. Nothing but good experiences with them.

Strengths:    Corrosive resistent, smooth shifting, light weight, does not break.

Weaknesses:    Side plates will bend with abuse.

Bottom Line:   
I've cycled through one CN7701 on two bikes in two years. It wasn't until I rode in the Colorado mud and muck for two days until I managed to chain suck one and bend some side plates. I had to abuse it to make it not work anymore, and it's time to replace it anyway. Unfortunatly it cost me a ride on the Colorado Trail, bummer. Next trip I'll hose off the mud at the car wash immediately after, lube the snot out of it, and finish my vacation, yeah! Worth the price, a quality product, and works flawlessly when drivetrain set up properly. After reading the reviews on the SRAM units, I'm ordering another.

Strengths:    AWESOME SMOOTH SHIFTING, STIFF AS A HUMMER. YOU CAN FEEL YOUR LEGS POWER ON THE TRAIL.

Weaknesses:    IT WORE OUT THE WHOLE DRIVE TRAIN SO FAST (SPECIALY THE REAR DERAILLEUR CERAMIC NEW PULLEYS AND LX 572 44 CHAINRING), W/O RIDING UNDER WATER OR MUD. +/- 550 MILLES

Bottom Line:   
AS I SAID, THIS CHAIN IS JUST FOR RACING, MUST BE CHANGED EVERY 4 RACES. WHY? SHIFTS SO NICE, SMOOTH AND RELLY FAST BUT IT'S A CHAINRINGS EAGGER. I WAS SORPRISED WHEN I REALIZED THAT THE BIG ONE WAS SO BAD, SO WORE OUT IN ONLY 3 MONTHS OR LESS. I'M GONNA CHANGED TO SRAM OR HG 73 AGAIN(BETTER EXPERIENCE).

Strengths:    Despite the bad rap, Shimano builds quality components. This chain is top of the line Dura Ace/XTR. A good chain is one that you lube and then forget it's there...this is that kind of chain.

Weaknesses:    None, in my opinion. Some people may find the lack of a quick-link annoying.

Bottom Line:   
Notice that the highest rated chains are way below other products' highest ratings. Why? Because the only time many people notice their chain is when it breaks. I've never broken a chain. I've snapped chrome-moly bottom bracket spindles, but not chains. Keep them lubed and toss them after a couple of years. Shimano supplies the "special" pins for the rather large section of the bicycle community that was born with 10 thumbs. You do not need to use them to have success with this chain. Just be careful when removing links (as with any other chain.)

SRAM chains seem weak to me. I've had to wait for friends who broke chains and it more often than not is a SRAM. They come with those quick-links because you need to use them more often! The Dura-Ace chain is the best chain on the market. Find one on sale.

Strengths:    Non

Weaknesses:    Proprietary Pins, Weak Links

Bottom Line:   
NOTE: this chain was a CN-7701, but it's not listed so I'm posting here.

8 Miles into my first ride on this chain and it bent, twisted then snapped downshifting to the inner chainring. It's just too thin be reliable.

Please note, I installed it per shimano directions for maximum strength, the drive train is completely 9-speed compatible, plus the derallieurs were just dialed-in before the ride and shifting flawlessly.

Other huge problem: the $2 apiece link pins. What a ridiculous system. After the chain broke, I pulled the broken links and popped it together with one of the chain's standard pins. Voila, it got me home, so why force the customer to use their spendy pins?

Save your money, buy an SRAM or SACHS or Huffy Chain at Wal-Mart.

Strengths:    None at all. Second shimano chain i've ever had and what another pile of s#!t this one was as well. Broke about 10 minutes into my ride. ( First 10 minutes i was ever on the bike!)

Weaknesses:    Everything!!!

Bottom Line:   
Shimano chains and cassettes are s#!t! They can't take torqe very well at all and if you ever have the misfortune of buying a bike with a shimano chain i feel very sorry for you. MY advise ; Take off the shimano chain, throw it in the garbage and buy a Sram, you will love it!!!

Date Reviewed: October 26, 2003

Strengths:    relatively rust resistant, does the job!

Weaknesses:    side plates can come loose, usually as a result of chain-suck or other trauma. I havent had any problems I had not experienced with other chains. Throw away the shimano pins and stick to KMC missing link connectors

Bottom Line:   
decent quality smooth riding quick shifting chain. Unlike all the sealed bearings amd moving parts on your mountain bike, the chain is right out there in the mud and grit. The more you clean it and look after it, the longer it will last. Do not wait until your chain wears out - it will be breaking too often and not shifting properly. Another thing that too many people do is run poor combinations of gearing resulting in bad chain lines which further stress and wear the chain prematurely.
bottom line - buy it, take care of it, and you will get your money's worth out of it

Date Reviewed: September 26, 2003

Strengths:    Strong pin connection much stronger than previous shimano pin connections than previous Hyperglide chain's. Shifts extremly well both front and rear derailers. Non corrosive surface resists rust. Very light noticable lighter than the XT model making it excellent for racers.

Weaknesses:    The links themselves bend very easy and it's fast shifting ability increases chainsuck. Which contributes to the bending of the links. The hyper glide pin connection system which you need replacement pins every time you remove it to clean it. Mine is dead now it bent on the trail today after two weeks of using it.

Bottom Line:   
I use to like Shimano chains but in recent years especially HyperGlide 9 speed models they have declined in both performance and relibablity and lifespan. But this is the last straw I bent this one after putting it on two weeks ago! For all it's light weight better shifting crap it's not worth it! I had to splice it on the trail today to get it working thank God I carried a spare length of chain or it's a eight mile hike back home. I have accually hade more problems with chainsuck with this chain than with my XT. Finally this pin system that they have developed is really the worst I mean every time you have to remove the chain you need a new pin and the pins are not cheap. No more Shimano chains for me I've already threaded up a new Wippermann 908 I hope this is a better chain than the XTR chain PEACE.

Strengths:    Lasts well
Strong
Those shimano pins are easy


Weaknesses:    The sticky stuff on new Shimano chains

Bottom Line:   
I have used the CN-7700 for over a year and the CN7701 for almost a year. They are both very similar 9 speed chains (only real difference being the riveting) 7701 has mushroom or circular rivets which is meant to be stronger.
The Shimano pins are easy to use and never break for me, in fact i never have chain trouble as i look after them. This chain will not last forever though. I measured mine after 6months are roughly 1000-1200km and it had sretched 1%or about 3mm compared to the new one (same model i bought).
Look after this chain and it will look after you.

Strengths:    Great chain
Shifts well
Lasts a long time


Weaknesses:    A chain break tool is required to remove chain

Bottom Line:   
This chain is absolutely great and I really don't understand all of the poor reviews on it. Are you people installing your Chains correctly? It pays to be a little anal when installing such a critical item on your ride.

I absolutely abuse this chain, mash it, etc. I do take care of my chains though and this might be the reason they last and don't snap.
