Zipp: LIGHT WEIGHT AND ROCK SOLID Zipp’s SL Speed Seatpost has become a favourite of road and cyclocross pros because of its light weight and dependability. 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. SL Speed carbon seatpost is available in 0mm or 20mm setback options.FEATURESUpdated distinctive Zipp cosmeticsDesigned using SRAM Exogram™ technology27.2, and 31.6mm in 400mm lengthAlso available the Zipp SL Speed DI2 Internal Battery Mount to hold a Shimano® DI2 seatpost battery within the SL Speed Seatpost, Mount sold separately as an accessory.Matte Black finishLifetime warranty SPECIFICATIONSMaterial (SP/ST): Unidirectional CarbonPost diameter: 27.2mm, 31.6mmPost length: 400mmColour (SP): Matte with white decalsHardware: SteelClamp Material: Al-6061Offset/Setback: 20mm
