I have been using Dura-Ace chains for over 20 years. I have never had a failure though I should note that I've only used this chain on road bikes. After comparing the performance of other chains to Dura-Ace, I have concluded that this is just about the best chain available. Other chains I have tested include KMC and Wippermann. Most chains I've used seem to work very well on the cassette. It's on the front that the Dura-Ace chains seem to outpace other chains.

As for wear, I have also been very pleased. I just replaced two CN-7700 chains after years of use. The Park chain wear tool indicated that they were still in almost new condition. The CN-7701 chains that replaced them showed no additional performance gain. From what I understand, the chain has been upgraded to improve "pin pull-out" by 50% and it has zinc alloy plated inner and outer plates with chromizing treatment link pin. Just what all that means is unclear to me. I do know that the pins have indentations to facilitate aligning the chain pin tool with the chain to reduce broken pins. I attribute much of the resistance to wear to hot-dipping the chaining in a really good lubricant comprised chiefly of paraffin and motor oil. The lube penetrates the chain completely and does not leave a dirt-grabbing oily coating on the surface. It produces a buttery smooth shift. I lube the chain approximately every 300 miles but I think it can go longer.

Shimano recommends and includes replacement pins for when the chain is broken for removal from the bike. In my experience, I think they are unnecessary. I use a Wippermann master link that is both easy to remove and to reinstall.
