It works great!
No complaints with the chain. Well worth the money. I use a KMC QR link without issue so far, even though it is not recommended.
Since I've got an all current generation Ultegra 6700DuraAce 7900 drive train, I thought I'd get one of the latest type of Shimano chains to compare it with the KMC's which I've been running over the past 2-3 years. This chain is better, particularly when downshifting the chain rings. No chainsuck issues at all (if you've ever had that happen, you'll appreciate the benefit of the asymetrical design of this chain). A definite recommendation!
Will always use this chain, prefer over Dura Ace, better value.
got 6,300 miles and still going on this chain
The Ultegra chain is as good as the most expensive and will last just as long. I get between 1800 and 2200 miles per chain. I've used Dura Ace, Sram and there is no difference in wear time or shifting, maybe a tad bit of weight but for the money I'll use the Ultegra. I have no dislikes about this product.
