Orbea or Cervelo

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

Can anyone tell me if the Cervelo P3 frameset is worth the extra £500 over an Orbea ordu.
Any comment would be greatly appreciated
Cheers
Phil
