Seatposts

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored seatpost color is available on the Zipp Service Course Seatpost. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering, we are proud to offer redesigned Service Course seatposts. - Material: 6061 aluminum - 2-bolt adjustability - Minimum insertion length: 90mm

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.

Kinekt suspension seat posts are the best in the biz and will make your JackRabbit ride as smooth as butter. Upgrade your JackRabbit with this seat post for a game-changing shock-absorber effect. Please note: this is a seat post and does not include a seat. We worked with the fine folks at Kinekt to create this seat post package designed specifically for JackRabbits. This seat post can support riders who weigh from 80-320lbs (36-145kg) and for taller riders from 5'2" to 6'6" (versus the 4'10" to 6'2" range of our stock seat post). The diameter of this seat post is 27.2mm (the same as our stock seat post) and the length is 350mm. This makes the seat able to go higher than our normal seat, which is useful when sitting on the Kinekt because the suspension causes the seat to lower when body weight is applied to it. This product is compatible with the following bikes: - JackRabbit OG - JackRabbit XG - JackRabbit OG2 - JackRabbit OG2 Pro - JackRabbit XG Pro - JackRabbit MG Renegade
