ZIPP Service Course Delay 20 mm seatpost

Features: - Better fit means better performance. - If your saddle is out of position, you’ll waste 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. - The unique clamp design also features downward-facing bolt heads that allow micro-adjustment of the saddle even after it is mounted. - For high strength, low weight, and efficient use of every gram, the shaft and head are not bonded but are 3D-forged from 6061 aluminum.
