SP20 Carbon Seatpost delivers precise fit with 0mm and 15mm offset options for Cervélo aero bikes
What Our Gearhead® Experts Are Saying:
"I’ve run both versions of this post. The 0mm offers a forward triathlon fit, and a 15mm on my road build provides balanced weight distribution. The carbon does a great job muting road buzz, and setup is clean and rock solid thanks to the integrated clamp head."
The SP20 Carbon Seatpost is designed for fit-focused riders looking to optimize their position on Cervélo's aero platforms. Available in 0mm and 15mm offset configurations, it provides a personalized fit solution, whether you’re dialing in an aggressive forward posture for time trials or achieving a more rearward, endurance-oriented position for long road days.
Crafted from carbon fiber, the SP20 delivers a balance of lightweight performance and compliance, reducing fatigue over rough tarmac without compromising stiffness. Its 350mm length offers ample adjustment room, while the integrated clamp head allows for secure, micro-adjustable saddle positioning.
The SP20 is the go-to seatpost for riders chasing aerodynamic efficiency, power output, or long-haul comfort.
