The Zipp SL Speed Seatpost is a favorite of pro's and weekend warriors alike due to its lightweight strength and dependability. Now even lighter, the Zipp SL Speed B1 Carbon Seat Post weighs in at just 170g thanks to the borrowed Exogram™ technology from Zipp's partner, SRAM. With the Exogram technology, the SL Speed B1's tube is as light and strong as possible, delivering some of the highest strength-to-weight ratings around.
The discerning cyclist demands that their seatpost be simultaneously adjustable, secure, lightweight, and fit-sensitive. With that in mind, Zipp offers the SL Speed B1 Carbon Seat Post in 0º or 20º offset, both available in either 27.2 or 31.6mm diameters. The single-bolt head is highly adjustable and easy to use, even when on the side of the road.
