Zipp’s SL Speed Seatpost has become a favorite of road and cyclocross pros because of its light weight and dependability. This new SL Speed offers the same range of adjustment as its predecessor, but at a lighter weight. Zipp’s engineers used SRAM’s Exogram technology to make the tube as lightweight as possible and optimized our clamping system for adjustability, security, and ease of use. What’s more, the SL Speed is available in a 400mm length to accommodate road bikes with compact frame geometry.
