I am debating between a 2004 Cannondale Ironman 2000 and a 2005 Ironman 2000. The 04 is new and is about $250 cheaper than the used 05. These are the differences that I see:

2004 2005

Forks Aero Carbon Slice si Slice aero premium

Tires Continental Grand Prix 3000 Michelin ironman foldable

Ultegra 9 Ultegra 10

Crank/BB Ultegra/Ultegra Cannondale Carbon Si/Hollowgram Si

Any thoughts from the collective on the components-to-price difference with the 04 new and the 05 used. The main differences I see are the 9 to 10 and the different crank/BB sets. Is the oversized BB that useful or should I put the 250 saved toward race wheels?

Thanks for any input,
