The guy interviewing is my friend and i made the subtitle in thai for him. The vid title is Behind the design of Specialized Tarmac SL6. This project S hired Peter’s team as a design consultant/ engineer. He oversaw the whole process from aerodynamic testing (the tarmac sat in the specialized wind tunnel for 6 months before optimizing other properties), to production.
The new Tour Magazine (german) tested 2018 aero and lightweight bike. SL6 uses the least watts amongst all around bike. The test used stock configuration. Some all around bike like Ultimate /R5 uses aero road bar. Most come with 35-50mm wheels.
Sl6 221 w
R5 223 w (aero bar)
Ultimate CF SLX 226 (aero bar)
Scott addict 229
Merida Scultura 233
Giant TCR 235
Lapierre Xelius 234
Trek Emonda 238
For context the fastest aero bike in this test is Cervelo s5
S5 207w
Madone 208w
New propel 209w
Vias 209w
Aeroad - 211w (with 454nsw)
F10 - 213 w (aero bar)
If you put an aero road bar on a Tarmac, it could save around 4-5 watts so the overall drag would be around F10/ Scott foil which is mighty impressive for an all around bike.
They also tested all bike with 404 as reference, didnt put the result in magazine though.

It's in this thread, with photos. 904g iirc.downhill1234 wrote: ↑Mon Jan 29, 2018 7:57 amThis video popped up a few days ago. Interview with Peter Denk. Some cool info on frame design and Rider First, along with aerodynamics. 35 minutes long.

I'm still trying to find what a non-Sworks frame might weigh, and how much more tire clearance these frames have.

That's exciting news, I'm planning on running a 38cm Zipp SL70 Aero which with the narrower position means I'm giving up almost nothing compared to a full aero bike. Add some deep section wheels and you'd be right there too.ichobi wrote: ↑Mon Jan 29, 2018 8:24 amThe guy interviewing is my friend and i made the subtitle in thai for him.

Thanks for posting this ichobi. I miss getting Tour magazine as they did some very scientific reviews. They dropped the English version a few months ago and canceled subscriptions.ichobi wrote: ↑Mon Jan 29, 2018 8:24 amThe guy interviewing is my friend and i made the subtitle in thai for him.

Any other interesting details posted on the SL6 in the review?
Not really much more to say. It beats the F10 in both HT and BB stiffness (so did many other bikes in this test, e.g. the TCR and MeridaScultura) They also added that the handling is very well balanced. (I can attest to this after rinding about 2000kms on SL6).
They didn't make it quite clear which S-Works SL6 they were testing but judging from the pic it's the UL version. Tour's scale weighted the frame in 56cm at 850g. The fork at 343g. It also ranks one of the highest in comfort. (as with Canyon Ultimate, Cervelo R5, Merida Scultura.).
What i gather from this test is that if you judge the bike by HT/ BB stiffness, comfort, handling, you will get equally nice bike from other makers. But when you add aerodynamic into the equation the SL6 will beat other by fair amount.

Could you post the stiffness data if its easy to share? No worries if not.ichobi wrote: ↑Mon Jan 29, 2018 6:29 pmNot really much more to say.

Thank you. Do you know what speed their aero watts are at?downhill1234 wrote: ↑Mon Jan 29, 2018 9:33 pmhttp://www.tour-magazin.de/raeder/rennr ... 45739.html

The page I posted didn't have watts, rather times to complete the 'course' at a given wattage.
The images at the bottom list aero watts for a given frame plus cdA graphs if you are interested.downhill1234 wrote: ↑Tue Jan 30, 2018 3:31 amThe page I posted didn't have watts, rather times to complete the 'course' at a given wattage.
It's listed in that test as being only 2 watts different to the new R5 and as you say both very good on comfort. Could you share what the HT and BB stiffness and tested frame/fork weight comparisons were between the R5 and Tarmac?ichobi wrote: ↑Mon Jan 29, 2018 6:29 pmThey didn't make it quite clear which S-Works SL6 they were testing but judging from the pic it's the UL version.

Just curious because I have one, thanks!
I won't be showing the full stiffness table. (They flagged me for that on this forum before as you need to buy the thing).
But for some figures
R5 HT stiffness 123 nm
R5 BB stiffness 77nm
R5 Fork stiffness 44nm
56 cm Frame 912g / Fork 346g
SL6 HT stiffness 105 nm
SL6 BB stiffness 76 nm
SL6 Fork stiffness 65nm
56 cm Frame UL 850g / Fork 343g
I rode both. Equally impressed in all regards. Would be happy to own both for many years (i own the SL6).
