I've used the CN-6600 chains for a long time and have always been pleased with their performance. However, on my rebuilt bike the new CN-6700 chain was installed. @ about 1,000 miles for no apparent reason a stiff link developed. In IMHO the bike comapnies are pushing the envelope toooooo far. Cutting the sides out of the plates of the links and hollow pins to make the chain a bit lighter. While the 6700 chain is asymetrical and supposed to shift better...I notice no difffrence in shifting from the excellent 6600 model. So as long as I can get my hands on the 6600 that's the chain I'll use. I ride about 6,000 miles a year and change chains every 2.000 miles.

I have purchased 4 Ultegra chains and have not had any problems putting them on or taking them off. They look good, work well, and strong. I would recommend this chain for any 10 (generic) speed bike. SHIMANO LIVES on bikes and fishing reels!

The Shimano CN 6600 10 speed drive chain predates the latest Ultegra level CN 6700 chain by one generation. It is a little heavier than the CN 6700 but I have seen breakeage problems with the newer version that I never saw on a CN 6600. I have observed instances of the newer chain's side plates cracking, some breaking off completely, and a chain failure that led to at least one crash. I have used the CN 6600 for years and thousands of miles of riding with no problems. It is very durable and utterly reliable provided that a mechanic follows the mounting instructions when installing the fastening pin. I usually ride 2000 to 3000 miles before the CN 6600 is worn to the point of replacement which is good for a 10 speed chain. Shifting gears has always been crisp and accurate throughout the life of the chain. I'll stick with the older chain until Shimano fixes the problems with its newer version.

This chain works fine. Shifts well, wears well, and if it matters, looks fine..... I mean it's a CHAIN, ya know.... It needs to transmit power from the crank to the rear wheel..... This it does just fine. I have a Dura Ace 7900 cassette on the back, an Ultegra 6700 crank and Dura Ace 7900 derailleurs, the chain works well and shifts good with all these. My only complaint is the fact that I don't like Shimano's connecting pins, so I use a KMC connector link. I don't really see any difference between this chain and a much more expensive Dura Ace chain except the appearance, and a couple grams of weight. If grams matter, buy the more expensive chain. If price, operation, and durability matters, buy this one, just as good for less money, just a couple grams heavier.

All my road bikes use Shimano 6600/7800 components and I have used the 6600 chains with good results for several years. Recently I discussed the compatibility of the new 6700 series chain with the LBS mechanics and they all agreed the new version does not work well with the older groups. Since my LBS does not carry the older chain anymore, Amazon was the logical choice.

Put it on my 105 drivetrain. Noticed a slight improvement in shifting. In all, it's a chain, it makes my bike go with no complaints.

I had some issues getting this chained shipped and Amazon was great with helping me get this worked out. Very easy to work with.
