Parts of Passion Carbon Seat Mast Head

Detail
Parts of Passion's seat mast head are among the very lightest available and feature solid, Swiss-engineered construction and impeccable finish work. The ISP mast is finished in a matte UD finish. The POP seat mast head is only available with 0 offset. The length of the mast is 55mm. Adjustment range is only 1-2mm so it requires a precise cut of the mast. However being the shortest of all ISP heads, it allows cutting less of the mast from the frame than any other ISP head.

Parts of Passion seatposts are manufactured in Switzerland, and feature a two-year warranty against defects in materials and manufacturing.

Installation
We highly recommend the use of a carbon assembly compound (such as Tacx Dynamic Assembly Paste) on the seattube/seatpost interface to limit the clamping torque required. A torque wrench is highly recommended as well. Recommended maximum seat collar torque of 6 Nm, and a maximum rail clamp torque of 5 Nm.
