I've been using Dura-Ace components since the early '90's. Prior to that I raced with Campagnolo. Since switching to DA I've never looked back. I presently ride a Colnago EP with DA 7800. I've always used the 7800/7801 chain. I just put a new 7901 chain on. This will now be my chain of choice. It is silky smooth, shifting is as usual, flawless and this chain is simple to install and maintain. I'm going to switch to DA 9000 over the coming winter but for now this is the only chain I'll use. Thanks PBK for, once again a great selection, service and price!

I decided to upgrade to this chain after my Ultegra wore out and I feel it's worth the extra dollars.The shifts are noticeably smoother and upshifts are a bit faster too. I would like to report on wear but I've only done 1100 kms but it would be fair to assume it should last longer than cheaper chains with the alloy treatment.All in all very happy with this upgrade and worth the upgrade

As I do alot of hill work I'm hard on chains so with the 7901 2000klms and the chain is done, which is not as good as the 7801 but then there is almost always a trade off for lighter weight.

The chain is quiet and the gear changes are very smooth with the 7900 Dura Ace group set. The chain normally last about 3500km to 4000km, but I always check it with the chain checker, as soon as it shows wear, I change it before it wears the cassette and cranks.

Great chain, works best with 7900 cassettes (as in new Dura Ace 10 speed 7900 series). didn't believe it would work better than the 7801 until I swapped over! Wears well with the new Dura Ace cassettes but not as long lasting as its predecessor (7801)

It feels like it's lighter than others, especially noticeable when shifting as it seems to just float from one gear to the next
