so do i go with a lesser grade carbon frame with lesser grade components or a aluminum frame with higher end components? or fork out the extra $ for a lesser carbon frame with higher end components? i'm looking at the giant defy, fit being the same on both.

6 of one, half dozen of the other.

With good tires and latex tubes, you can get a damn nice ride out of a well-designed aluminum bike ( but lose some bling factor). Lower-grade components are getting so good that it is getting harder and harder to justify the extra expense of DA / Ultegra, etc.

However, the rule of thumb is usually get the best frame you can and upgrade components as needed.

Article about carbon frames and the manufacturing process in Bicycling mag a few months back. According to the article a lot of terminology used by the manufacturers is a lot of hype. Most modern carbon frames are pretty good. I had a Klein at one time that was a real nice riding bike, but I bought a Colnago Master X-Light and I liked the nago's ride better. You might take a look at the Ridley Fenix. Performance bike has them on sale with Ultegra for $2399.99. I know nothing about these bikes, but if I was in the market, I'd consider one. What I did is test rode a couple of bikes. Carbon bikes can ride quite different. If I was to consider an al bike, I'd look at a Cannondale Caad10. Good luck.

What model Defy? What else are you looking at? Is $2500 (just throwing something out there) your limit?

Aluminum has a fatigue life so depending on how long you keep the bike it will eventually break. For most people that can mean 20 years.
Carbon finer properly engineered and correctly made does not .

the defy composite. one has the ultegra and the other has 105. i don't think they make an aluminum defy with ultegra but i think there are other makers that have the same geomery in an aluminum frame with ultegra.

Depends how sensitive you are to differences in ride "feel" (this is why you test ride them) but typically I'd say go for option with higher end components.

Here's a question for all of you out there with experience: How much of an upgrade is DA from Ultegra, and Ultegra from 105? I know the more expensive parts are a touch lighter and have bling appeal too, but are they functionally better?

Not substantially, LSD....more of a difference between 105 and Ultegra than Ultegra to DA. A lot of the $$ for DA goes to stuff like cassettes, etc which adds very little performance advantage. You could argue it is a negative since the lifespan is probably less.

If the carbon bike has roundish tube shapes and a bottom bracket shape that is pretty standard I'd stick with Al.

Carbon frames are interesting when they take advantage of the shaping you can do with carbon. That is where they can make the ride different. That difference can be noticeable sometimes to some people.

i've never had carbon and i've had some pretty used ultegra on a nice aluminum frame. the shop will probably give me a good deal on the defy composite so that's what i'll go with (if it actually happens).

Last month my 3 year old Masi 3 V (carbon, made in Taiwan) broke in the bottom bracket shell area. I got a replacement as it was covered by their lifetime warranty (still had to shell out 600 bucks for an "upgrade").
This month my 8 year-old (but I only had it for 5 years) Yeti ASR-SL (aluminum dual suspension mtb) broke with a nice crack next to the weld at the the top tube's "V" bend. That frame is toast and I'm outta luck on that one since Yeti only warranties their frames for 2 years and I'm not even the original owner.

I'm bummin'. Steel might be the best material.

If I had a choice, I buy a frame and have my LBS build it up. The only original part I have left on my '07 Trek Madone 5.9SL is the headset. Eventually every sticking thing I had on the stock bike was replaced. I would have saved money in the long run.

Steel is the best material, but it's getting expensive. My '02 Colnago Master X Light frame (with carbon fork) cost $1700. Now it's around $3000.

steel would be preferred but it's hard to get the right geometry without going custom.

Am I correct that it's still a lot cheaper to buy a built up bike? Just remembering the original post, which seem to be cost consciousness.
If you like steel, consider ti, too. Such a sweet ride, never rusts, and lasts.
