In that you're riding a Pinarello Prince, I assume you have a regular seatpost and standard road type position on the bike. To use standard aerobars comfortably(i.e. Syntace SL) most people would have to move the seat forward, or use a forward-position seatpost. Another option is use a "shorty" type aerobar and your current road type or "big slam" position.
