Zipp Service Course SL Setback seatpost is perfect for an all business race bike. It's low-profile postclamp allows the saddle to slide farther back along the rails. This unique design also offers 20mm of setback and micro-adjustment with downward-facing bolts that are accessible even if the saddle shell covers the top of the seatpost.
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 – not bonded together. To further reduce weight, the 220g (275 x 27.2) Service Course SL seatpost uses titanium bolts and more intricate machining than the regular Service Course post.
