Specialized Command Post BlackLite

On every trail, whether littered with technical descents, grinding climbs, or smooth rolling sections, Specialized's Command Post BlackLite lets you attack. It controls your seat height with the flick of a handlebar-mounted lever so you can maintain your flow at all times. There are three positions to choose from: up for climbing; down for jumping and steep descents; and a middle height when you need to pedal, but you want extra maneuverability too. The seatpost is sealed for reliability, and is controlled by a standard derailleur cable.
