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 carbon Service Course SL seatpost is specifically tuned to be more shock absorbing than the "comfort" seatposts on the market, while still passing our strict internal MTB strength test. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you'll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt-head accessibility. The Service Course SL seatpost makes it possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types. - Distinctive Zipp cosmetics - Unidirectional Carbon fiber tuned for ride comfort - Lightweight clamping system - Lifetime warranty

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
