The paint jobs on these bikes are always such a disappointment. From that angle, the R5 looks ok, but the yellow/green accents are terrible. And when you realize that they covered the inside edge of the frame in that color too, you just want to vomit. SO close, yet so far away…

From the data released by Cervelo, which happened to keep the rim and disc brake curves on different graphs. Fixed it for them
SO when did they drop the tall head tube phase that they went through for a while? The front end of those bike certainly looks better now.
The r3 is the same stack as the last 2 generations, R5 dropped 8mm in comparison.
I like the navy color scheme with the red accents. I think it would’ve looked even better if they used red instead of blue on the inside of the fork (kind of like they did a couple years ago) Though I’m not sure what to think of how they used the red on the downtube.
It’s disappointing that Cervelo continues to put crappy stock wheels on their bikes. Mavic Aksium Elites on a bike with a $5000 price tag? A two hundred dollar wheelset with a 17mm internal rim width doesn’t belong on this bike. They were headed in the right direction when they started putting Hed Ardennes on a lot of the models, but this is a step back in the wrong direction.
I pulled the trigger on a new R5. It should arrive today. I can’t wait. I’m currently on the previous version of the R5, and it’s been my favorite bike by far. I can’t wait to see how the changes feel.
That version at least comes with Enve 3.4 wheels, although built around Formula hubs. I’ve got a set of Martindale 50mm wheels I’ve had for a couple years that I love, so I’m going to have to decide if I want to keep the Enve’s or sell them.

Interesting…so, despite the cleaner cable routing and potential to “shape” the fork and frame around the disc calipers, the disc version is still ~.002-.005 m^2 higher CdA across the board? And that’s not even including “power to rotate” differences of the wheels?
Imagine if the rim version had better integrated brakes built into the fork (like a Madone, for example)…
BTW, where was this data located?
Wonder if the disc version was tested with the large, bulky SRAM eTap Hydro hoods?
Those have to add some non-trivial drag.

They would still suck.

So mature…
You are asking important questions. I was just playing around Tom.

I know this is a joke, but I think an accurate response would be “that would suck”. The R5 isn’t meant to be an aero bike, it’s meant to be an all-around race bike. A better question would be how would the aerodynamics change on the S5 if they integrated the brakes - I’ve got to imagine they’ve done testing on this and determined the gains are minimal.
I can say I’m glad the R5 has standard brakes, because it makes swapping wheelsets much easier.

Well…if we’re just playing around…then my response is: “Just like YOU!”

And yet, they keep improving the aerodynamics of it…I think the claim is the R5 is ~.010 m^2 CdA improvement over the old one…so, it’s not like they ignore it 
In any case, the point is that of ANY of the models of bike that would have a CHANCE for the disc model to be the equal in aerodynamics to well appointed rim model, it would be the R5/R3 models…and yet, it didn’t.
So much for the idea that they were pushing in the P5X intro that switching to discs allow them to make the overall system more aero :-/

I thought it was interesting as this is one of the first newly developed bikes with an aero focus to have discs. Not just chucking a disc fork on and making a rear triangle mod to an existing design. So if there was a chance for discs to be faster in the current format (flat mount) we’d see it on a freshly designed bike from proven aero experts.
You need to look outside the English (or American) speaking world for the good info http://www.duckingtiger.com/the-all-new-cervelo-r-series/
R3 Data
Old rim brake still generally faster than new disc

It makes sense on a TT bike, but yeah a $5K road bike??
I’m not sure how important aesthetics are with bikes, but I’m finding a lot of the Cervelo range looking quite dated now. I’ve had 2 P2s, great bikes, but the shape is old, it has barely changed in 10 years, similarly with the P5. I used to lust after those… Look at some of the Felt or BMC bikes, they just look so much better.
