Compatibility, Size and Fit
The listing describes other diameter and length choices, but this page is for the 27.2 mm diameter, 400 mm version. Do not assume other seatpost sizes fit the same frame. Confirm the frame’s required diameter and that the saddle rails match a listed clamp size.
Safe Use and Important Precautions
The listing specifies a tightening torque of 4 Nm but does not identify the fastener. Confirm the applicable torque in the seatpost and frame instructions before installation. Do not rely on the stated value if those instructions differ or the correct fastener is unclear.
Choosing the Correct Version
Match the diameter and length to your frame, check the saddle rail dimensions, and account for the 25 mm offset when setting saddle position.
Before You Decide
Confirm the 27.2 mm frame fit, 400 mm length, 25 mm offset, and saddle rail size. Check the applicable instructions for the stated 4 Nm tightening torque before installation.
