Zipp s Service Course range is designed to offer top performance without breaking the bank. The Service Course Seatpost has been redesigned and improved to offer lightweight and a great fit at an affordable price. The secure and low-profile clamp has extra-long saddle rail support meaning the saddle can be slide further forward or further back. The clamp design also features easily adjustable downward facing bolts and a micro-adjust head, allowing easy adjustment even with the saddle fitted. Unlike other entry level seatposts which use a bonded shaft and head design, the Service Course is 3D-forged from 6061 aluminium, giving a cleaner look and lower weight as well as being stronger. Simple but effective, the Zipp Service Course Seatpost is a great choice for those looking for high performance without a high price. Lightweight, Strong, Affordable SeatpostSecure, Low-Profile Saddle Clamp6061 Aluminium Construction350mm LongWeight From 245g
