CN-6600 Ultegra 10-Speed Chain | bike-chains

Perfect . ;)

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.

Replaced my road bike chain with this Shimano 10-Speed chain. Great quality with little to no noise. Rotates smoothly, shifts well and works perfectly on my Specialized Road bike.

I didn't realize how noisy my triathlon bike chain had become until I replaced it with this new one. The original chain was the previous version of this CN-6600. It lasted a long time between road rides and trainer rides. These Ultegra chains are a great value for the price. With this new chain installed my drivetrain is back to silent running!

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.

This was an upgrade from my previous chain. IMO, it is excellent. It was easy to change the chains. The chain is very quiet.

My husband needed a new chain for his 10+ year old Trek bike and it fit great. He's happy pedaling again.

There are so many different kinds of chains. The web site had all the right info so I knew I was ordering the right chain. It works great and my bike once again shifts and runs smoothly again.

Originale Shimano x cambio 10 V Dura-Ace . La confezione contiene 2 pin ma ne va utilizzato solo 1 .

Just as expected. Very well packaged to safeguard lubrication of the chain.

What I expected and fast delivery.
