The Zipp Service Course SL Seatpost is engineered to seamlessly integrate with Zipp’s renowned Service Course SL handlebar and stem lineup, offering cyclists a cohesive upgrade that harmonizes performance and aesthetics. Designed for road riders seeking precision and lightweight efficiency, this post combines advanced materials and ergonomic innovation to elevate your ride experience across diverse terrains and disciplines.

Crafted through 3D forging from high-grade AL-7050 aluminum alloy, this seatpost boasts exceptional strength-to-weight ratios while maintaining structural integrity for long-lasting use. Its internal shaft is meticulously machined to shed unnecessary grams without compromising stiffness—ideal for competitive racing or endurance adventures where every gram counts. The slim-profile micro-adjust cradle features a dual-bolt clamp system that allows millimeter-level saddle positioning adjustments, ensuring optimal comfort even during prolonged rides or aggressive sprints. Unlike traditional designs, this setup simplifies fine-tuning without requiring tools, making it perfect for quick adjustments during training sessions or on-the-go tweaks during races.

Engineered with titanium hardware throughout, the post resists corrosion and fatigue better than standard aluminum alternatives—critical for riders tackling wet climates or grueling training schedules. With a minimum insertion length of 90mm, it provides ample stability for frames with limited seat tube space while maintaining compliance to reduce vibration feedback on rough roads or gravel paths.

Whether you’re chasing speed in triathlon events or building endurance on century routes, this seatpost delivers responsive handling and sleek aerodynamics that complement Zipp’s Service Course SL cockpit components. Its lightweight design pairs seamlessly with race-ready bikes or all-day comfort setups, offering versatility unmatched by heavier carbon alternatives.
