Replacement Seatposts for Comfort, Fit & Performance

A great ride starts with the right position. Our collection of replacement seatposts at 365 Cycles helps you restore comfort, adjust your fit, or refresh an aging setup with durable, high-quality options that fit a wide range of bikes.

Whether you’re replacing a worn post or upgrading for better adjustability, our seatposts are engineered for stability and strength. From alloy to carbon, each model is designed to deliver the perfect balance between weight, compliance, and durability  so every mile feels smoother.

Find the Perfect Match for Your Ride

Cycling comfort comes down to details. Pair your new post with one of our ergonomic comfort saddles to ease long rides and reduce road vibration. If you’re securing a new setup, explore our reliable seatpost clamps for consistent grip and alignment.

For riders looking for lighter, performance-driven builds, our carbon seatposts deliver strength and vibration dampening for next-level comfort.

Quality Gear, Expertly Curated

At 365 Cycle, we don’t just sell parts, we ride them. Every product in this lineup is chosen by cyclists who know the difference that proper fit and component quality can make. With fast U.S. shipping and trusted brands, 365 Cycles helps you keep your bike feeling new, season after season.
