Fizik's Cyrano R1 Carbon post is everything you could ever want from a seatpost: simple, light, and easy to use. It's crafted from carbon and aluminum for a fantastic blend of feathery low weight, stiffness, and durability. It features a long lower clamp to better support saddle rails and a short upper clamp and adjuster wheel to maximize adjustability. It's also compatible with both round and oval saddle rails.

The Cascade dropper post pays homage to the Cascade mountain range, home to some of the best riding in the PNW. This post is a workhorse: it’s super reliable, loved by our customers, and now features multiple travel options. The Cascade provides dependable up and down service for the miles to come, and maintenance on the Cascade is easy (like all our droppers). Plus, external routing at the mid-cap ensures your cables are kept nice and tidy during up and down actuation. You can find sweet upgrades to the Cascade’s OG dropper design on the posts featuring 150/170mm of travel. These models have larger diameter stanchions, making them stiffer and lighter… which is sweet because who wants a bike part that’s heavy and too compliant? These longer travel models also come with an added DU bushing to combat seat wobble, because let's face it… the only thing that should be wobbly on your bike are your legs after a long ride.
