Bike Seatposts – Road, Track & Fixed Gear

Explore our selection of high-quality bicycle seatposts at Miclo Bikes, including new and used components for road bikes, track bikes, fixed gear bikes and custom cycling builds.

Our collection features a variety of carbon seatposts, aluminium seatposts, aerodynamic designs and classic vintage seatposts, suitable for different frame types, riding positions and cycling disciplines.

Whether you're upgrading your road bike, building a lightweight track bicycle or restoring a classic steel frame, choosing the correct seatpost is essential for a secure saddle fit and comfortable riding position.

Discover seatposts from respected cycling brands such as Thomson, Cinelli, Nitto, Campagnolo, Deda, Zipp and Ritchey, where available, alongside rare and hard-to-find vintage cycling components.

We offer different seatpost diameters, lengths, offsets and saddle clamp designs. Always check seatpost diameter, frame compatibility, minimum insertion depth, saddle rail compatibility and manufacturer specifications before purchasing.

Many of our used and vintage seatposts are individually sourced and available in limited quantities. We aim to provide clear photographs, detailed specifications and honest condition descriptions.

Based in London, Miclo Bikes offers UK and worldwide delivery, with collection by appointment available.
