These are my favorite chains, and this is the best price. I'm not a masher - but I am a strong pedaler. The ultralight chains never last for me. These on the other hand are durable as all get out, they stay cleaner than the ultralights, they cost a lot less, and they aren't noticeably any heavier.
After breaking the SRAM chain, twice!, that came with a new bike, I replaced it with a KMC and have problem-free ever since. I've been using KMC chains for nearly 20 years on various bikes and I think I've never broken one. I commute by bike every work day of the year and ride as much rocky singletrack as I can sneak in (30 miles/week). KMC chains are simply the way to go--I replace them yearly or every other year, depending on the bike/miles.
After torturing one of KMC's 8-speed chains on my single-speed for a while, I decided to give the x9 a go on my geared bike. Not many miles yet, but so far so good. These chains are easy to work with, durable and well made. Comes with the quick-link. They also seem to run very quiet. The fit and finish on the KMC chains at this price point just seems a lot better than comparable SRAM and Shimano chains. I'm a fan.

Great chain for the price. Better than buying from SRAM or Shimano for much more money to get similar quality. I've been running mine for almost a whole season (almost 1000 miles) with no breaks. I started with a fresh drivetrain and still haven't had any issues with mis-shifting or ghost shifting. Seems to be a very strong chain with minimal stretching over nearly 1000 trail miles so far. KMC's quick-link is easily as good as what you would get from SRAM.
