The Dual-position seatpost lets you switch between road and aero positions on the fly, giving a full 50mm of fore/aft adjustment. The seatpost's forward position replicates the steeper seat tube angle of a tri bike, opening your hip angle and letting you ride comfortably and powerfully in the aero position.
Redshift seatpost is 27.2mm, if your seat tube is smaller (I am afraid this won't fit), if your seat tube is larger you may want to add a shim: available here.
