Seatposts — Carbon & Alloy

Seatposts are the cheapest way to change how a bike looks and one of the easiest to get wrong: diameter, offset and clamp design all have to match the frame exactly.
We make aero carbon seatposts for integrated-frame road and gravel builds, and alloy posts for general use. Common diameters are 27.2 and 31.6 mm, with 0 or 15–25 mm setback; length is cut to your frame’s maximum insertion mark.
Before ordering: confirm the diameter with a caliper rather than the frame spec sheet, and check the minimum insertion depth — an undersized post in an oversized seat tube is the most common cause of frame damage we see.
Seatposts ship as part of OEM framesets or as standalone spares for after-sales. See OEM & ODM terms for how spares are packed with a container.
