I am looking to buy my first bike, with the intention of doing tri's. I was going to get a road bike at first, but I have found a great deal on a tri bike. (Cervelo Dual with Dura Ace)

My question is do most people ride a size smaller tri bike compared to their road bike?

(I am 6'4'', and have been test riding road bikes that are 60cm. The tri bike I am looking at only comes in 58cm, and there is no way I can test ride it. I would plan on getting it built and then professionally fitted if I bought it)

Yes, most people ride a size or two smaller than their road bike. But with the different way bikes are sized, I would highly suggest riding the bike or something similar before buying it. I have seen too many people lose big money buying bikes blindly.

See if the shop where you are going to get your fit has a Serotta fit bike or something similar. Have them set it up like the bike you are wanting and see if it might work for you.

another newbie question: Why do people choose a smaller bike? Is there an advantage despite possibly a suboptimal fit?

To get an optimal fit most need a smaller size Tri bike. Head over to Slowtwitch and read all about FIST fitting to learn the differences in fit, but the short answer is you need a smaller top tube becuase you are sitting much more forward and you need a shorter head tube becuase you are a lot more leaned over and there needs to be room for armrests.

You kind of have the process backwards, you need to get fit, then buy your bike according to the fit, not buy a bike and then get it to fit. Even if its a smokin deal, if you are compromised getting it to fit, then it won't be a good deal.

I was originally going to go with the cervelo dual, but I have found a 07 kuota k factor bike for around 1600. this would be a complete carbon frame with dura ace. I have read that kuota has a more relaxed tri geometry, that I feel would fit my bigger body better than some of these aggresive postions of other bikes.

any feedback on the kuota k factor?
