Lowdown: PNW Components Rainier Dropper Post
Dropper posts have risen in popularity over the years as riders have discovered the benefits in almost all aspects of riding. But cost and reliability have remained an issue, as many cost $400 and up with reliability continuing to be an issue. As a result, some riders still hold out, or at least don't install them on all their bikes due to cost and maintenance.
PNW Components is an upstart component maker from Seattle, which has a wealth of bike industry experience. They've taken their know-how and overseas manufacturing relationships to deliver a dropper post called the Rainier. The post is infinitely adjustable and has an externally routed cable. They have two posts, one in the hard to find 27.2mm diameter with 80mm travel for $275; the other a 30.9mm with 120mm travel for $270.
