Ready for every mile of road, this seatpost comes equipped with a hard-wearing 6061 aluminium construction for an excellent combination of strength and durability on your road bike. Zipp has also kitted out this model with a 6061 aluminium clamp and steel hardware, so you can benefit from a tight and secure hold to your saddle rails whatever the conditions. Another highlight is its etched Zipp logo finishing, which gives it a sleek appearance to complement your ride.
