By using a single piece, forged head and shaft instead of bonding separate units, Zipp was able to make its Service Course SL Seatpost even more Super Light. The titanium bolts also contribute to weight loss, and the fact that they’re easily reached from below means that you can simply adjust your saddle position once it’s installed. The clamps themselves feature a low profile which provides more clearance and a wider range of fore/aft adjustment.
