Before You Decide
Confirm the correct seatpost diameter for your bike, then check whether the 400 mm length works for your saddle position. If you want an adjustable head, make sure that feature matches the setup you need.
Check Saddle Mount Compatibility
The adjustable head description does not specify which saddle rail shapes or mounting hardware it accepts. Before selecting a seatpost, confirm that the head can clamp the rails on your saddle and that any required hardware is compatible with the chosen configuration.
