This chain shifts smoothly and is quiet. Paired with a new freewheel, it made an old road bike (1980's era) feel almost new. Easily as good as more expensive Shimano chains and seems smoother than Regina narrow chains I've been using on several 6- and 7-speed bikes. Can't yet speak to durability, but after 1500 miles of winter riding, it hasn't seemed to stretch or wear yet. I haven't had any issues with the "missing link", which is probably an added potential convenience.
