PRECISION AND INNOVATION
Zipp’s Service Course seatpost is lightweight and strong for security and designed to offer a precise fit at an affordable price. It also provides easy tool access to the downward facing bolt for easy setup and micro adjustments after it’s mounted. Better fit means better performance to make you faster. An out-of-position saddle means wasted energy with every pedal stroke. The secure, low-profile clamp allows the saddle to slide farther back along the rails, and with 0 mm and 20 mm setback options, it’s possible for nearly any rider to achieve the perfect fit. For high strength, low weight, and efficient use of every gram, the shaft and head are not bonded but are 3D-forged from 6061 aluminium.
