I buy a number of these chains when they are on sale and each will last me about 2,000 to 2,500 miles. I clean the chain every 100 miles and lube with a dry teflon spray which gets out the majority of the road gunk and provides another smooth ride and performance stroke. Park tool has a nice chain tester to determine best time to replace, prior to waiting and have the chain slipping or jumping gears. Ride on... smoothly!
Be careful when you buy this Shimano chain. Three of the last four that I bought or checked at the store already showed 0.5% of chain stretch out of the box, using a Park tool. In other words, two thirds of the wear was already present in the new chain. I gave up and bought a KMC chain which was solidly at 0% wear.
New Shimano 6700 chain works great with a new replacement Shimano 6700 cassette. Both purchased from Bike Tires Direct. No complaints from this happy bike rider.
Just a rock solid, well priced, chain. Have been using the Ultegra on all my bikes for years. Clean, lube, replace when my Go, No Go chain checker tells me to. No need to over sell it!
I decided to try Shimano chain on my Shimano 105 group bike after using other brands for many years. Shifting is flawless and crisp. It was a great decision. I fully recommend this chain.
Okay the chain works great and is the high quality we expect and get from Shimano. My only caveat is that installation of this chain is not as easy or foolproof as with the SRAM or KMC products. I learned the hard way-the link pin must be inserted correctly or the chain can break. In my case the chain broke as I was climbing a hill, and locked up in the rear derailleur which then tore through the chainstay of my titanium Litespeed on its maiden voyage. A bitter pill for sure, for which I don't blame Shimano. I simply want to warn users of this system that installing this chain correctly is important. Since this disaster I have installed these without a problem and run them on more than one of my bikes, so all good now. But a tough way to learn I hope other buyers avoid.
I guess a chain could be awesome but not sure. Got this one to replace worn Dura Ace chain on rain bike.
New chain works great. And the price was extremely reasonable.
In fact I sold some Dura Ace 10 speed chains (new) on eBay, bought and extra one of these and had extra $$$ in my pocket afterward. That's a win-win!!!!
