I was wondering if anybody had any info on the bike what model and if this is actually true.
Many tri bikes have an adjustable seat post, including the Cervelos. You can generally go somewhere in the neighborhood of 75-80 degrees depending on setback.
The point of being steeper is to get your front end lower.
On a road bike you may be further back to use more glute and hamstrings and get more power, especially climbing. On a TT bike you can sacrifice a bit of power to improve aerodynamics and gain speed.
As already mentioned, though, if you go steeper then you'll want to drop the front end. If you're adding clip on bars to a road bar then your stack height is already going to be super high (and not aero) and you're likely not going to be able to lower it enough, even if you have spacers under your stem for your road fit.
So, to reiterate, you're either going to have an awkward road bike or an awkward TT bike. Either is better than nothing, of course, but if you're serious about triathlons and speed then you're likely going to need a properly low front end assuming you've got the form and flexibility to get actually get low.
