The A2 doesn't seem worth the money. The parts are on the low end. The A1 and A0 have better parts but I think the frame is aluminum so $3000 seems like a lot of money especially when you can get a P2C for $2500 with Ultegra and $3000 with Dura Ace.

Is that an '07 or an '06? Is it new or used? And the biggest question of all... does it fit you? As a comparison, here's a Cervelo Dual on Ebay...

It hasn't closed but it's an '06 with similar components and has a pretty good reputation for an entry level tri bike.

If you like the bike and it fits you, buy the bike. If you're looking for someone to tell you it's a killer bike and you should buy it, it's an ok bike and I'd consider other options.

Some people buy multiple bikes for different races. I've had three since high school and friends that have had 20 since high school. My coach has 230, but he rents most out to the team. He personlaly will switch between 4 since 2004.

So, it comes to money, addiction and racing.
