It seems like there is no longer a Shimano CN-7901 10-Speed Chain available for purchase. When I received this chain the box states its for Dura-Ace, Ultegra and 105 10-Speed drive trains. Its a bit confusing but the price on the so called Ultegra chain is affordable. I guess I can now just replace my chain more often. My bigger concern is that Shimano apparently is abandoning continued 10-Speed component support.
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.
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!!!!
If you're tired of looking for the weakest link (I always wanted to use that phrase in a sentence . . .) then perhaps its time to replace/upgrade your chain! I have two bicycles with Shimano 10 speed components (105 and Ultegra ) and opted to replace the chain and cassette, swapping the 105 components for Ultegra. This was a no-brainer . . . great components at a phenomenal price! You really can't go wrong with the Shimano Ultra CN6701 chain - replace your chain today!
This is what I use with my Dura Ace set up. On my 2007 Trek 5.5 Madone, I have replaced original cassette with a Shimano Ultegra CS-6700 10-speed and used this Shimano Ultegra CN-6701 chain. Learning how to install was done using youtube videos and luckily I got it on the first try. You will need a chain tool to size and install a new pin. For the price, I go with Ultegra over Dura Ace any day.
