What to Compare Before Buying

  • Seatpost diameter: Confirm that the frame requires a 25.4 mm post. A general fit claim for several bicycle types does not establish compatibility with every frame.
  • Length and insertion: Check that the 350 mm length provides the needed seat height while meeting the bicycle’s insertion requirements.
  • Saddle attachment: Confirm that the post’s clamping arrangement is compatible with your saddle and current setup; specific clamp details are not provided.

Before You Decide

Verify the frame’s required diameter, the 350 mm length against your fit needs, and saddle-clamp compatibility. Use the marked safety line in accordance with the bicycle and seatpost instructions.
