The E-Post Ti seatpost is fully isolated from mini-impacts and vibrations by 3 elastomer blocks. Two of them are placed inside and secure the seatpost inside the frame. They can be expanded by tensioning the adjustment bolt with a maximum tightening torque of only 5Nm. This solution is much more durable for carbon than a conventional collar requiring 20Nm tightening torque. The third elastomer block is placed between the frame and the post. This elastomer is inserted 40mm inside the seat tube and forms a 9mm thick pad outside.
