Specialized is known for their ability to create carbon fiber components that offer a blend of capabilities and functionality at competitive weights with great reliability.

A cylindrical aluminum head assembly, meanwhile, makes fore/aft and tilt adjustments super easy with an easy-access, single-bolt design. It is equipped for 7x7mm round metal alloy saddle rails, but comes with clamp plates for 7x9mm oval carbon versions.

Available in various diameters, offsets, and lengths the S-Works Carbon Seatpost is a great option for road, gravel, cross and XC MTB use. Always follow rated torque specification and proper seatpost and rail clamp positioning.
