Just went to a carbon frame from aluminum frame, so where is the big speed gain??

It's called marketing. Every year you give the pros the latest, lightest most expensive gear and send the subtle message to the weekend warriors that they can perform like the pros if they spend the money for that kind of gear. It's done in lots of sports markets.

This! I feel less beat up on my carbon bike than on my aluminum bike. Besides the carbon matrix material, the chain and seat stays of the carbon bike I ride are further shaped to vertically flex a tiny bit to absorb high frequency vibrations. I can really tell the difference especially on rough tarmac. I did research though and read a lot on this forum for the better part of a year, so I knew what I was and wasn't getting from my new carbon bike.

Riding my carbon bike vs steel bike on the same route is so much more comfy.

I've been riding an aluminum frame Trek for 7 years and finally splurged ona new Cervelo S2 with upgraded Ultegra crank. My first ride was yesterday and I did a 17 mile loop I've done a bunch of times and was expecting to blow my normal time away with this new ride. So I get done and check my time and no gain! In fact I have done the loop faster on my old Trek atleast once. Needless to say I'm a bit disappointed but maybe I need to get use to the new gearing and fit before any gains are realized? Am I being too quick to judge here or did I spend $3k and really did not gain any mechanical advantage?
Thanks
Thanks
When I saw the thread title, I just had to look.

Well, OP- by the diversity of conflicting opinions shared here, it should reinforce the fact that most of the small differences between bicycle frames and components truly come down to a matter of the rider's perception; and have little to do with actual performance. Performance comes from the rider. Aesthetics/feel/perception come from the bike...along with very minute gains in speed, which would only be noticeable to a racer.

And it's possible that a slight difference in tire circumphrence is masking a small improvement in speed by the OP. Add a couple of centimeters and that speed will go up.

So true! My Klein rides like a Cadillac, and yet is stiff as a board. -and with 23mm tires, no less.

bt - This may be true
Metal Pedaler - I appreciate your sage like advice and dose of reality
I do notice a different ride than my aluminum bike and different sounds (not really relevant to speed but oh well). The bike is much tighter and probably accelerates better than my old Trek. Typically I ride between 16 and 18 mph on average and by the end of last season I was averaging slightly higher (18-19 mph) for a 30-40 mile ride. I'm guessing if I put more time in and get back to that form I may get more benefit from the carbon but time will tell. In the end I will ride more for sure as I have decided not to train for tri's anymore and just ride the bike this season.
If I don't get faster then hell i'll just buy new wheels, my kids will have to pay for their own college education I guess because dad needs carbon fiber...

Interesting thing, too- for any given advantage you may get in one area from a particular bike or component, you often lose as much in another area- i.e. lighter bike/lighter wheels may accelerate faster....but less weight also translates to losing momentum sooner/losing speed on descents; Deep-dish aero wheels may cut through a headwind a little easier....but you'll get buffeted in a crosswind.....

Comfort-wise, my carbon and steel bikes are very similar. Stiffness (especially in the BB area) and to a lesser degree weight are where I feel the difference. My hardtail MTB is the only alloy frame I own these days.

Actually, reducing the small flapping of your bike jersey by wearing a tighter one will yield far more aero benefits than $2500 Zipp wheels. Those wheels give at BEST 1minute per 60 minutes of racing, and that's assuming you're 25+mph the whole time.

Serious answer: somebody did an experiment on a velodrome with a powermeter to find the biggest bang to for the buck, or rather the most watts saved per dollar spent. If I recall correctly, it was clip-on aerobars followed by an aero TT helmet.

Really, I'm in for a set of clip on aero bars and a goofy TT helmet then. Maybe a skin suit so I can properly embaress my kids in front of their friends.
