The ride quality is not his strong point. On a 5 bikes back to back comparison on a panel of 10 riders (for a french journal) it always scored quite low (on purely subjective points... but that what makes ride quality)...

EF riders usually prefer the evo3 (to the point they almost never followed Cannondale recommendations that they made for each stage and rider type.

Looking at the chart above, it looks like the evo3 was tested with the knot 45 wheels. Wonder how that bike would test with the deeper wheels like 404 or Knot 62 wheels--would it be nearly as aero as the SL7 at that point?

Yes the Rc 10 is in HMX carbon fiber, the ultimate is in HMX SL carbon fiber.

But very thanks for your data!

Do you have the stiffness numbers for the SL7?

I'd like to confirm what I'm seeing on the matrix - the Scott Addict R is roughly 2 watts slower than the Cannondale SuperSix2, and 10 watts slower than the SuperSix3? That seems off - the Scott has hidden cables and semi aero tube sections vs the SS2 round tubes, exposed cables etc. I would expect the Scott to be roughly equivalent to the SS3 (though we know that looks are sometimes decieving) as they have many of the same design cues. But I also note that the Scott Addict has no mention of wheels tested - are they the 35mm stock ones?

Two of biggest differences are going to be frontal area (bar shape/width, HT diameter, stack, etc) and what wheel/tire combo each bike came with.

For example, the Addict has the equivalent of a chonky straight 1-1/2" steerer and a HT to match.

Good point, that looks really wide!

Is it possible that at Tour they've not had their hands on the new Emonda yet?

two observations - Cannondale route the cables in the front of the headtube I believe, giving them the opportunity to create an oblong tube section at the head tube - an immediate benefit. Second, the fork crown/tire interface is quite a bit more open on the Cannondale, which may mean there is less of a choke point for air trying to pass through/around the assembly.

Kind of a bummer, as I like the rest of the design cues on the Scott. But physics don't lie.

In a thread that seems to be focusing on aero properties, there is no difference between the regular HMX and the HMX SL. It's just weight but again, the thread seems to be about aero properties.

I wonder where the first generation Venge would fall on this list, if anyone has a back issue of this magazine. I remember there being hearsay about the 1st gen Venge being similar to the Allez Sprint... but I'd like to know for sure.
interesting discussion here at viewtopic.php?f=3&t=158016&start=15
2015 tour aero indicate 1st gen venge is at 213w with the old firecrest wheelset while the 16' venge vias with the new firestrike wheelset is at 204w
the new firestrike wheelset is said to be 1-7w faster, giving a net difference of 8w to 2w. a user had an experiment and concludes a difference of 3.8w between the two.
