Size guide

One type of seatpost comes in different diameter sizes to fit various bike frames and riding styles. For road bikes, a 27.2mm diameter is most common, providing a balance between strength and weight. Mountain bikes often feature larger seatpost diameters, such as 30.9mm or 31.6mm for added strength. You can determine the correct seatpost diameter by measuring the diameter of your current seatpost (at its widest point) or by consulting your bike's specifications.

Offset

Offset

The seatpost offset refers to the distance between the centerline of the seatpost and the centerline of the saddle rail clamp. A zero offset aligns the clamp with the seatpost, while a 15mm offset positions the center of the saddle rail clamp 15mm behind the center of the seatpost. The offset affects the saddle position and influences saddle position and rider comfort on the bike.
