Ryder Seatpost SL 30.9 x 400 Black
What Is It?
The Ryder Seatpost SL 30.9 x 400 Black is a standard aluminium bicycle seatpost designed to hold and adjust your saddle height on bikes with a 30.9 mm seat tube diameter.
It is a non-suspension, rigid seatpost, meaning it provides a direct connection between saddle and frame for efficient pedalling. The “SL” typically indicates a lightweight aluminium construction, making it suitable for MTB, gravel, and hybrid bikes.
The 400 mm length gives good adjustability for riders needing more seat height range or deeper insertion compatibility for modern frames.
