EA50 SeatpostEaston's entry level seatpost is packed with impressive features. We start with a durable EA50 aluminum alloy shaft and add an easy to adjust, two bolt clamp. Don't be fooled by the sleek lines and subtle aesthetics this post offers as much function as form. The forged aluminum clamps offer rock solid stability and 10 millimeters of offset will accommodate any bike fit, making the EA50 seatpost a smart upgrade.
