Next triathlon item to come
I've been thinking, with the creation of Ovals new aerobars and forks which instead of having a single piece have two outside pieces for wind to travel through. When is this going to happen with seatposts, this seems way more logical than an aerobar. Imagine two pieces which your legs are more or less sliding against, and then a big gap inbetween those pieces, the reduction in frontal area for my bike would be about half that of my current seatpost. Also, John Cobb said a big problem with current aero seatposts is the legs creating turbulence. With a seperated seatpost you would keep a majority of the air away form the legs. I think for increased stiffness the two seperate airfoils would sit directly under the seat rails. Maybe I'll sketch something out and send it to Anne Hed or John Cobb.
