Speaking about the "penalty" for aero - there sure seems to be in most of the comparisons. For those who were able to see the chart on page 5, in the overall rankings for the combined "performance" of those pairs of bikes - the non aero partner was ranked better (and generally MUCH better) overall than the aero partner in 7 of the 12 paired situations. It was a tie with 3, and the aero beat it's partner in only 2 situations.......but one was the Stork whose "aero" model truly sucked in the aero category but shined in comfort and stiffness (so a mis-categorized frame). So in my view the true aero frames were outright winners only once (8%). For those that didn't see the chart that performance ranking included the effect of aero but also comfort and stiffness where it counts.

So it's not as simple as why not......but is it worth it?........

Added side note about the Giant aero "module" - I seem to recall a review posted by a major source (Velo? CyclingNews?) that suggested the aero improvements were significantly positively influenced by the integrated stem and bars - which conflicts with a post here suggesting that it may be a disadvantage (compared to the Zipp used with the others). The article as I recall suggested that the lack of choices (bar angle and shape) was a significant compromise the end user would have to put up with.

Don't get me wrong - I am in support of aero - but not extremes that result in an overall detriment to the overall picture.

Not performing in the Tour test does not mean the Aernario is mis-categorised.

It was just that much better than the other aero offerings in judging on aspects unrelated to aerodynamics.

Would like to see a similar test for 100 mile rides comparing ultra stiff vs compliant.

So all im seeing here is stuff that is so tightly clustered given the length of time of the test that aero wise your frame choice is largely irrelevant.


Which is what I have been saying since aero frames arrived on the scene, accept of course when it comes to wheel and tire options. Then choosing an aero frame become highly relevant as in it becomes a major nuisance. Mostly just heavier, and less comfortable. A true detriment for 95% of the people that ride them. Just try your S5 on some fresh chip-seal. :P

And who spends 4 plus hours exposed and solo in competition?? Don't we have time trial bike for that nonsense?? :noidea:

Whole thing is a bit of a scam IMO.


I agree with this although, im not a sprinter & when it comes to winning a race. Alot comes down to a TT Effort in a Solo Break.

Measure new frame weights to a .1 of a gram with/without paint, but don't waste my time with meaningless aero data. Everybody knows bikes are only meant to go up 25% gradients at 3mph.

The fact is that actual weight is measurable in an absolute way while actual aero performance is rather debatable.

Aero is measurable, the physics is just more complicated than m x g x h. All I'm saying is you can't argue that a 1% performance improvement is worthless outside of a pro level and then claim dropping 20g is in anyway significant. You can argue the measurements may be inaccurate or inconsistent, but the "performance gains are too minimal to matter" argument doesn't hold.

It's not all about aero. If a pro is in a 5 hour stage and has another one the next day, the last thing he/she wants is to be on a potentially harsh riding aero frame that causes fatigue.

The equation for having it all; aero, compliance/comfort and sharp handling is actually quite simple...

It goes a little something like this:

N+1
