3D forged from 2014 T6 aluminum using proprietary 3D forge tooling for a thinner oval wall, the Deity Tibia seatpost is durable and light. The oval inner forge increases strength in stress area. A splined clamping system with spring loaded guts held together by a one bolt installation process is how the seat stays put. This incredibly light and strong seatpost comes in at a claimed weight of 242grams. That’s light!
