Without looking @ aero data, the Shiv TT has been mighty successful under Tony Martin. The new boardman looks ridiculously quick too
it’ll probably vary just a tad depending on the rider/position. at the tip of the sword many of them are pretty close.
P5
But Tour tested the Canyon Speedmax to be just as fast. But oddly its fastest configuration was with an 808 on the back rather than a disc.
Tour tested a P5 Six. Not UCI legal.
Hard to say, depends on the yaw angle histogram you experience during the ride, and possibly your body shape too.
P5, Shiv TT, Trek Speed Concept, Giant Trinity, Scott Plasma, maybe some of the new frames like the Fuji Norcom Straight and others are all up there. BMC is close etc etc
I feel that most high end TT bikes are so comparable now in terms of aero that what is more important is geometry in relation to how it fits you, comfort and compliance for long distance rides, and how easily it’s maintained.

Jack, how much slower is an older generation design (think Ridley Dean) compared to top-of-the-line framesets with the integrated bayonet style fork? Something like 100 grams at 25mph, or would it be more significant?
Also, i notice that you didn’t mention Felt DA. Is there a reason for that?
Finally, anyone has a list of frameset weight of these things (couldn’t find one on aeroweenies).
Thanks in advance

Absolutely +1. Many of these frames are essentially the same design with very minor tweaks. Rider fit and position (or lack thereof) can negate any significant aero advantage due to frame design.
This chart is kind of a handy reference for that. The P4 is similar to all the new modern superbikes
that is bike only data though, no rider aboard. So that ~100g difference might be less, or more on some of the new bikes with a rider aboard.
The P5 for instance has features that make it test a little worse with nor rider aboard compared to other frames, but better with a rider on it.
~50g @ 30mph = 5w = .5 seconds per kilometer

damn, difference of 300 grams at 10 degree of yaw at 30mph? That’s still like a good 175 grams at 25mph…
The reason why i got interested all the sudden is that i may come over to the dark side one day, and by dark side i mean time trialing ;). There’s a Ridley Dean on competitive cyclist going for $1200 for the frameset, which is why i was wondering. Otherwise, there are various other more modern framesets out there for ~$3500.
One other question is regarding the base bar compatibility. Say i get a speed concept; would I be able to install aero bars from other companies on there, or would i be limited? Also, while we are at it, anyone ever done a comparison of the basebars? Preferably with a dummy on there.
Not a lot of tests of the new bikes out there. But the fastest frame is probably the Canyon at the moment. Of course it is not available in the U.S. marketplace.
How does the Slice RS stack up against the p5/shiv? I assumed it was more or less on equal footing … but that tour test is confusing me …
It appears to be slower than the P5 according those the German tests.
Well the speed concept you can get in the 7 version and use any bar you want, not sure about the 9.
But the bars on the 9 are beautiful, I would use em =)
Also, you can make up some of the gap on older frames, like the P2 for instance, use the latest cervelo fork, use a ventus aerobar, omega brakes, do the cable routing mod.
Put a decent dent in the difference.

P5, Canyon, new SC and the Slice RS

Data means nothing when it’s not Tony Martin riding it. Whatever he rides will be the fastest bike. As are Wiggins’ and Cancellara’s. Which means the differences amonst bikes are insignificant (at that level) compared to the differences among riders.
75 gF more drag and Tony Martin wouldn’t have won the title. That’s 2.5% of the total drag, a minimal difference
Ah, well on the day of the worlds elite 2013 TT in 2013, the difference between Tony Martin and the rest of the field was great than the difference between good frames.
However, the difference between 2nd and 3rd place (Fabian and Wiggins) was not.
In 2012 the difference between Tony Martin and Taylor phinney was only 5 seconds.
It doesn’t matter what level you are at, time trialing is a game of seconds and you want to get all of them if you want to win. Tony Martin isn’t just out powering the field, he is going through rather extreme aero measure as well. He even specifically sought to remain with a specialized backed team when high road ended.

Jack, thanks again for the response. One thing i didn’t realize was that the Ventus has an integrated stem while the others are just base bar and extensions. Certainly makes things a bit interesting
btw, it looks like the Speed Concept 7.5 has changed a bit this past year as it seems to be a bayonet styled fork, though i’m not as sure about UCI legality of this thing . You know, after all, i don’t want to be mistaken for a tri-geek
