i did search this subforum but found nothing on it so i'd ask anyways.
I saw this in ebay and was wondering if you can use a time trial/tri frame for your road bike? i know unless it's ridiculously aerodynamic then it won't be conventional... but the frame below looks like a regular road bike frame.
What would be the difference?

Why did he put "Cervelo" in the item title?
Those sorts of shenanigans always make my hackles rise.
Edit: Scratch that. The Giant website told me that the seat tube angle on that bike is 75 degrees. A tad steep for some, but might work for you...

Nope - that question has definitely been asked in the past.
(quick search)
Here.
Here.
There was another thread from someone who bought a frame (ebay?) and then wanted to use it for a commuter, but I can't find it.
Edit: Didn't look at the link before... the Aero-2 is the aero road frame, not a TT/Tri specific frame, so the seatpost angle isn't an issue. Would make a nice fast road bike.
Edit2: Bugger... seems it's not quite the same geo. as the road frame, it runs a steeper seat tube angle. So... if you like riding fast, it might be good, but if you are after a more cruisy bike then it might be a real pain getting the saddle further back.

I ride, therefore I am. But don't ride into harm's way.

@twizzle: i stand corrected, didn't find these 2 thread but thanks for posting.
btw what does SWMBO mean in the below contexts?
"I would keep the CELL but it needed to be sold to appease SWMBO into allowing a new bike. It went yesterday, hence the advert is gone."
i haven't ridden a tri bike but i noticed they have steep seat tube angle. so here's what i can decude: greater(steeper) ST angle = faster bike on flats, pain on hills and long ride; lesser ST angle = slower to pedal bike, good on hills and long rides.
what's a normal seat tube angle anyways? here's another one i'm looking at with 73.5deg.

73 to 74 degrees is considered "normal" for a road bike.
Bikes geared towards triathlons tend to have 75 degree seat tubes, because they're designed to use particular muscle groups. A steep seat tube angle puts your legs back and torso forward, allowing you to lean forward enough to effectively use the aforementioned muscles.
