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.

None.

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.

@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.

Your decoding skills are pretty good.

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.

ahaha... grass is always greener the other side but pros n cons. by end of the day, you'd want to have someone sit beside you while you watch cycling channel.... your bike lol.

saw this article... i think i'll stick to road bike frame as i wanted to train my quads. i have fairly skinny legs and i want to grow my leg muscles.
