What is the truth behind bike weight? Does it really help THAT much?

I'll take a guess for the $5000 prize.

Could it be a 2006 Ridley Damocles?

Yeah 105 looks about the same so I bet your right, I moving up from a shimano 2200 ft. deraileur,tiagra rear, and sora shifters to all ultegra sl

I think it is great that the average joe / josephine can buy the same bikes on the pro tours. I have passed some of those bikes on the way back to the parking lot, but it is still nice to see that they are available for purchase.

(Just kidding with you)

Absolutely, its what makes bicycling a bit more real vs. sportbike racing. Speaking of real I always thought of myself as the average Joe but I keep defending my right to commute 26 miles round trip on a bike in winter to the average Joe and I still don't own anything with spandax but that will change soon enough.

So I will agree there to a point. That being said I believe the benefits are a bit more than just a placebo effect. In fact it may be fair to look at the bigger picture. For most consumers when upgrading to lighter wieght there's also the upgrade of better groupo/components.I do believe the shifting does tend to get a bit more slicker at the high end for example. Not to mention the thought toward designing for added stiffness and areo.

If you really like bicycling enough to spend time on a forum or wear skin tight clothing then I believe it's perfectly okay to spend some dough on a nicer, racier ride. Perhaps it won't make you faster then again you may use less power to get up that same hill. Or you may find yourself having a easier time keeping up with your friends. Personally I'm looking forward to my new carbon Cervelo. It's going to be 7 pounds lighter than my Raliegh and an upgrade in everyway, that in it self may be the best part. Plus I think its awesome that one can actually buy the same bike that won Paris Rubaix. I suppose folks on here can be negative as far as freedom of speech goes but I can't help to think that your all just jealous because you just too cheap, eskewed by logical reasoning to treat yourself to that so called placebo effect. To all you that think wieght doesn't matter, good luck riding whatever it is you ride and more importantly maintaining that excitement riding brings you. Fear not for if remember you on the day you decide to step up you game with a lighter bike I won't be the type of poster to rub in a double standard.
Hey, there's absolutely nothing wrong with buying any bicycle you can afford simply because (choose all that apply)
you want to
you think it looks good
you will have more fun riding it
you will go slightly faster and therefore might win or keep up easier on rec. rides
etc.

I repeat: absolutely nothing wrong. We all do the same to varying degrees. In fact, even though I'm slow and weak, I'm thinking at 55, I should buy my "dream bike" simply because I can and if I wait any longer, I might need a tricycle with a grocery basket on the front. Why not own a $5000 bike sometime in your life even if you only go 15 mph?

The only point I was making is that it is simply false when people claim their better bike and / or wheels made a 1-2 mph difference (or the extreme 3+ mph claim). Just won't happen, except due to "new bike" or "placebo" affect (which might indeed increase speed - but it's not because of the bike).

Hey have fun with your new bike. Yes, I'm jealous! It sounds NICE. I'll bet it will be a kick to ride.

No, no, no, you have to wear Assos cycling shorts if you're going to ride a Cervelo R3. It just wouldn't be right to wear cargo shorts on that bike.

Truth is, the same rider and team would likely to have won the same race on another bike.

What do I ride? Well, lets just say that I also have a top end bike that has been associated with multiple major race wins. But I recognize that it's just a play toy without the engine power and nothing to brag about.

Damn! My computer only reads in 0.5 km/h steps. No wonder I am not seeing my speed improvements.

Ha,ha you know it funny because I used to think that people spending anything more than 100 bucks on a bike were crazy. I'll be lucky if this bike doesn't end up costing me more than 5k. It's still in the process of being built. I don't know what to say except I'll ride anything that has wheels but this bike makes me want to join a bike club show off my cute butt. I'm actually kind of intimidated by it. It just isn't the kind of bike you can lean against poles or leave behind for a quick snack at the store or use for shopping. Bicycling for me in the past several years has been equally if not more practical than sport. Actually taking money from the sale of my Ninja sportbike to buy it. I'm 33 years old and I hear you with not wanting to wait till I'm crippled.

sogood, it's obvious you need a better computer. The Garmin GPS unit would be the answer, except that it adds 150 grams and a lump of drag on the handlebars, likely offsetting the savings on that new wheelset that you're trying to measure

When you say another bike winning the same could that be anything made of any material so long as the fit was the same as well as geometry. You seem pretty to know more than me but I'd bet that a bike with 531 heck 853 steel tubing would be fast but not have the edge to take the win given the new carbon bikes dominating this race.

Like a team mate of Eddy once said, 'Eddy can win on my bike, I can't win on his'. O'grady rode a good bike with LOTS of support in a field of lots of good bikes with lots of support. One more thing, more races have been lost due to equipment than have been won.

Have fun on your new bike, make sure you ride it lots, like Eddy says.

You need to keep a beater bike. As you point out, you won't be able to let the Cervelo get out of your sight, except in a secure lock-up. Not the bike for a run to the shops.

Ah, I knew there's a physical reason for that. Every time I mount my Garmin eTrex on the bar, I felt that I was slowed by something. Must be that exponential air resistance on speed being factored in.

How about comparing with other CF bikes of other teams?

You'd be wrong betting that, because any edge the new bikes have isn't necessarily an advantage at all. About the only real edge that new bikes can have is an aerodynamic edge, and frame aerodynamics are well behind human corpus, wheels, and helmet when it comes to aero influence. Stiffness? There have been exactly zero studies that have shown frame stiffness to provide any performance benefit at all. Weight? Weight's a non-starter and is not on the list of things that win races. I'm not sure what else you'd consider to be part of the "edge" that new bikes have.

10-speed cassette hubs, brake-shift combo levers, 1 1/8" fork steerers, slant-parallelogram rear derailleurs, and splined bottom bracket tapers all get my vote.

On the other hand we've lost stock frames sized in 1-cm increments and handlebar stems in 0.5-cm increments.
