Scott Plasma2 LTD — ($9,350)

Scott Bikes rocked the annual Hawaii Ironman bike count in 2009, largely due to the successful debut of the Plasma2 LTD last year. This bike is an aero speed demon that rolls smooth thanks to the Scott’s attention to detail on the spec. While the top-end components (including a SRAM Red drivetrain, Zipp wheelset and ceramic bottom bracket) make for a one-of-a-kind ride, it also makes the Plasma2 one of the priciest tri bikes on the market.
