“He had outgrown the stock post. With the extension, his riding position feels much more natural.” Typical parent feedback. Comfort may vary depending on rider height and posture.
Why add a STACYC seat post extension
As kids grow, the stock seat post can quickly become too short.
The STACYC 185mm seat post extension allows you to extend the seating position to provide a more comfortable and better-suited posture for taller young riders.
CNC-machined from solid aluminum, it offers excellent durability while maintaining a clean, premium finish that integrates seamlessly with the bike.
