Please select options


If your saddle is out of position, you're wasting energy with every pedal stroke. To counter that, Zipp's Service Course SL seatpost was created with input from professional bike fitters. The Service Course allows the saddle to slide farther back along the rails, offers 20mm of setback and its easily easily-accessed, micro-adjustable bolts provide the ultimate in adjustability. For high strength, low weight and efficient use of every gram, the shaft and head are 3D-forged from a single piece of 7075-aluminum, and the SL also features intricate machining and titanium bolts.
