|What's the difference between a time trial and a tri bike?||Bad Mojo|

The reason I ask is because I'm looking for a single purpose aero bike to just go FAST. I will use it on flat rides from around 10-40 miles. I want a steep seat tube angle (78 or at least 76.5). Aero bars are a must, and aero wheels are high on the list. I ride a 55c road bike, so I think I should be able to find a tt/tri bike/frame with 700c wheels. Should I be looking for a time trial bike or a tri bike? Or is there even a difference? Any advice???
Thanks for your help,

|Is there a difference? Basically no, if you spend an appropriate amount of time on the bike. You seem to already have your mind set on what would traditionally be termed "tri" geometry. The reason being that most road riders who spend a fair amount of time on a standard road geometry bike find switching to the steeper geometry uncomfortable, which usually translates to slower riding. At 55cm, you could go either way with wheel size. Make sure you dial in your body position, as it represents more of the drag you experience riding than wheels or a steep seat tube angle.|

|No difference. some tri use 650c wheels and turn the seatpost backwards to push the seat forward even more- but they have to run afterwards, so it helps. On the TT, you don't need the seat so far forward. |
The other guy is right, your body position and comfort will determine your speed and aerodynamics more than the bike. If you buy a TT/Tri bike, take the time to have yourself properly fitted by someone who knows.
