The patented Dual-Position Seatpost lets you ride a true aero position on a standard road bike, without sacrificing your normal road position. Along with the Quick-Release Aerobars it provides the benefits of a triathlon or time trial bike without the additional bike or price tag. The key to riding powerfully and comfortably is proper saddle position and since you can switch between road and aero positions on-the-fly while riding, you can always choose the best riding position for every part of your ride. Benefits: - Transform your current bike—switch from road to aero position on the bike you already own - Ride with ease—no more time and energy wasted switching from road bike to aero bike Details: - Linkage design lets you switch between road and aero positions seamlessly while riding - Choose the best position for every single climb, flat, or descent - Maintain proper leg extension in both road and aero positions - Saddle moves forward 50mm, corresponding to approximately 4 degrees of effective seat tube angle change - Aero road riding position optimized for proper handling on a road bike - Simple, durable two-bolt saddle clamp allows infinite saddle tilt adjustment and reliable clamping - 16mm rearward setback (road position) - Check technical specifications for compatibility

The X-Fusion Manic post uses internal cable routing and was designed around a low-profile seat cradle and seal collar to fit a broad range of frames.

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

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.
