The Good: Power-link, light weight, price, works very well with other Sram/Truvativ components
The Bad: Some people complain they break, but I haven't noticed the problem
Overall Review: I've noticed the Sram chains available in Europe are made in Portugal. These I've noticed are better than their similar Asian cousins, that are made in China. I've noticed that with a mostly Sram (rear derailleur and cassette) drive-train are really slick but that Shimano chains jump around a fair bit, so better to stick with the same manufacturer here as the rest of your drive-train. Power-link rocks and is easy to use and better than KMC missing links.
