The EC70 seatpost utilizes a forged aluminum head bonded to a carbon fiber shaft. This combination delivers an impressive strength-to-weight ratio in a more affordable package than the flagship EC90. This seatpost also benefits from Relief-Area Design (RAD™) and Taper-Wall™ technology for pin-point strength, stiffness and durability. The clamping mechanism gives 15-millimeters of offset to help riders fine tune their bike fit.
