Kalloy Seatpost ATB Ø27.2mm 400mm - Mat Black

This ATB seatpost from Kalloy is the SP-375 model with a diameter of Ø27.2 millimeters and a length of 400 millimeters. It is designed as a strong, reliable replacement featuring a patented head saddle clamp design. The ATB label indicates the mounting style of the head, making it a practical fit for many city, trekking, and MTB builds that utilize the common 27.2 millimeter diameter. Crafted from durable 6061 aluminum, it strikes a perfect balance between low weight and everyday toughness, while the matte black finish provides a clean, modern look that complements most frames. The extra-long 400 millimeter length allows for more insertion and a wider adjustment range, ideal for achieving extra saddle height without sacrificing stability. With a no-spring design, it ensures a direct ride feel and simple maintenance.
