How heavy is heavy? and what is your setup?
I run a P5 with disc, deep front, etc. at about 20lbs, so definitely not lightweight.
If you want lightweight, go for something with less frame material, shallower wheels (202/303/etc.), rim brakes, and high end components (SRAM Red/Dura Ace). I had an alum P2-SL that weighed in around 15lbs like that. It wasn’t nearly as fast, but it was considerably lighter
I have had a 17 lb p3, a 23.5 lb felt and now a 20 lb p3. all go the same up hill and over x distance because you ride steady not with accelerations. that said.
most of the frames are the same wt or close, if you have integrated cables there is likely a heavier frame for the extra carbon, etc.
You will make your bike lighter more with the following then with the frame.
wheels
aero bars
bottom bracket and cranks.
add ons ( water bottle, tools)
after that the wt difference is so small it doesn’t matter much.
seats ,pedals, bar tape, cables, brakes, cassettes.
so if you want light buy the many third items light and that’s it.
The last generation Cannondale Slice (just prior to the super slice) in the Black Inc. frame when built up correct is incredibly light. It easily and rivals and beats “normal” road bike builds and is lighter than many of the aero road bikes on the road right now.

If your bike weighs more than 10lbs why are you even racing?

The absence of accelerations does not eliminate the additional power needed to raise more weight up a given hill in a given amount of time. And you will not get the lost time back in equal measure on the way back down. The performance cost of weight is reduced with less acceleration, but it’s not eliminated even on a level road (increased rolling resistance) and certainly not on a hilly course.

Yes and Andy Potts rode it.
Always go as aero as possible but if you can achieve the same position with lighter components and you have the budget, have fun.
Aero and Light is right and finally the industry is moving in this direction with both road and tri bikes.

I forgot he did. There were a couple of other pros that did too (Michelle Vesterby won a Challenge race). I found the fork, frame and seat post weight of regular high-mod frame (1,605 grams or about 1 lb lighter than anything listed on the chart above)…the Black Inc. frame was even lighter. Not the most aero frame available but then position and other things probably have more of an impact on drag than the frame.

I’ll second this. I saw one of these built up in a 57cm frame over on Weight Weenies somewhere in the 17lbs range with a rear disc wheel and a 50mm front wheel. Direct mount brakes so a prime candidate for EE Brakes.
