Zipp Service Course SL B1 31.6mm x 330mm 0mm Setback Road Bike Seatpost.
Zipp have taken their pro-proven Service Course SL Seatpost and made it better and lighter. The redesigned post - weighing just 220 grams for the 0 setback - is lighter while providing security and a precise fit. It’s also designed for easier tool access to the downward facing bolt for easy setup.
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. This 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 a single piece of 7075 aluminium. Zipp use Titanium bolts and utilise more intricate machining than the Service Course seatpost. Finished in 2-tone polished Black.
