I purchased a used Soma Smoothie that was decked out with Ultegra components. After a few months into the rainy season, my drivetrain and shifting became dodgy, which turned to be due to a stuck link. Unfortunately, I couldn't un-stick the link, so I purchased this chain, which was identical to what I had. That made for a quickeasy replacement. Things are smooth, once again. )
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.
