Road Cycling - Why Pros and cyclists will not build their own road bike?

I recently have read a post here "Ebay project bike complete!"

I see most of the time people are getting a new road bike for 1500 to 2000 dollars. Why are the cyclists not willing to build their own bike with their favourite frame and parts? I mean you can use a good Italian, Reynolds steel or Carbon frame and built up a decent bike with mix Shimano and Italian parts. Many people said it is better to buy new for money saving. I agree but the money is not well spend.

For example, I would build a bike with Cervelo Super prodigy or Lemond Zuich frame, Chris king head set, Carbon fork, FSA K-force carbon seat tube, carbon K-force crank head set, FSA carbon handlebar, Ultegra brake calipers, 105 front derailleur, 105 rear derailleur, 105 STI fight deck, Speicallized Tri-spoke 700C wheel set and Dura-Ace 9 speed cass.

In the market, you can hardly get a lite wheel or Tri-spoke with FSA K-force stuff and 105 in a high quaility steel bicycle. Note: I use some 105 stuff to balance the cost of the high quality stuff.

I just don't have the tools and the money. If I am willing to spend US 1500 to 2000 dollars, I would buy my favorite parts and frame on ebay and put it in a big box and let the bicycle shop to assemble it. I would be more happy for spending my money this way.

Am I insane or smart? I don't mind people call me stupid, just be honest and share your opinions.

Hey, its your money... so I'd say do what you please with it.

As for me, I did this:

On Ebay, I brought:
--Dura-Ace 10spd gruppo; Deda Newton handlebar, stem, MagicStick post, Mavic Ksyrium Elites; Michelin Pro tires, Conti Tubes

Ordered a 2005 Cannondale Six13 from the dealer.

Then I put everything together myself in my home bikeshop. Life was awesome to build something that took me 18 months to save up for!

I've built 2 bikes this year and am working on a 3rd. I am constantly acquiring and changing parts from bike to bike. It's an obsession and a huge part of why I like cycling.

Doing it yourself is extremely gratifying. And you don't need a $1000 set of tools if you already have some basic screwdrivers, pliers and wrenches.

As Phil Knight says, just do it.

Having a warranty on everything, a service warranty from the shop, and everything work together nicely right out of the box is really nice. Mixing parts, even if they are all fairly high end, usually creates some quirks in my experience.

For the same new components. It is cheaper to buy the whole bike. If you want the mix and match that you listed, fine. That is the way you will have to go.

I read an article one time where they priced out building an entire car by buying individual parts. A $15,000 car was over $60,000.

Maybe the fav frame and parts are at the lbs,already put together.Most get the bike and replace stuff as they wear out,go on sale or just to upgrade and look,its almost a built bike. Its hard to find time enough to ride so i dont want to build anything but i think its pretty cool for thoses who can/do.

I've probably owned 25-30 high end bikes over the last 25 years and they were about 50% bought complete and about 50% built. The good ones were built up either by me or a shop. Not that they were physically any better, just that a lot of really high end stuff is often bought separately as a frame, fork, groupo, wheels, saddle, stem, bars. etc.
