Longevity

Came standard on Spec. Sequoia 2008, 5 years and 7000 miles later. No problems. I do clean and lube after every ride with Gold Chain lube. And try to shift without any load. Also am not a power rider. So either I am lucky or my care and riding style make a difference.

Smooth shifting and cheap

Perhaps it could last a little longer

After 3070 km, 80+% offroad, chain was almost 100% worn and replaced. Zero problems during these hard 3000+ km, but... You have to respect your equipment if you are looking for carefree rides. I don't shift under heavy load and I try to keep my chain always clean and well lubricated. Especially during summer conditions, since sometimes I manage to collect almost a tablespoon of dust after a 30 km ride! Not sure if it should last a little longer, but it is cheap enough for what it offers, at least for me.

always breaks!

I have never had a Shimano chain that DIDN'T break...sometimes only one half the plate will pop off, the edge of the plate will grab the derailleur arm, and break your derailleur and in most cases bends the hanger.
I don't understand how a drivetrain company can have such crappy chains...
Connex all the way!!!!! Never had one break!!!

The HG CN 73 came with my Trek Bike and 2000 miles later I decided to clean it. Removed it from the bike, cleaned with solvent, oiled and replaced. I ride 60 miles a week with 2000 feet of climbing and no skips or missed shifts with my ultegra 9 speed shifters.

No Master Link. When removing the chain, you have to be careful not to push the pin too far out or you will never get back into place.

I was surprised to see all the bad reviews. I am guessing the bad reviews are a result of poor maintainence, shifters and chain are not matched or superior leg strength while shifting under power.

Can't think of any when a chain leaves you stranded.

Maybe 50 miles of riding and the chain broke!

Grrr

Came stock on my bike... ridden snow, mud, dry, rain, desert.. hasnt failed me yet!

None that I can see

This chain came on my bike.
I have ridden it near and far for over 4 years and it has never had a hiccup.
I use a very light viscosity synthetic motor oil to lube my chains, and they still shine like new (and have 0 rust or kinks).
I would buy this chain again when a replacement is needed!

Came new with my bike in 2008. I've abused it for 4 years, some offroad, but mostly riding it as my resistance trainer all year round.
I do about 250 kilometres a week.
Awesome.

Stretches fast very springy

This chain is not worth the money I had 2 and I got less than 1500 km out of both of them together. So I bought a kmc and this chain for the same price is much stronger. I dont know why you would want to spend the money on this chain when you can get a better one for the same price. I dont think you should buy this one

Can't think of one.

The chain came stock on my brand new Giant Anthem. Damn thing broke on my third serious ride. This chain has no business on any mt bike, let alone the Anthem.

Use this chain for coasting downhill only, and you'll be fine.

Less expensive than some other chains.

It breaks.

Chain came stock on this bike. The first chain broke within a year; decided it was time to replace it anyway and bought another one. Has broken twice again this year during street/path riding. The first time I had a chain tool, the second time I didn't. I'm going to try the SRAM PC-991 Crossstep this time and see if it can handle the punishment my 5'2" 115 lb wife dishes out.
