21.5 watt Saving over the previous S5 VWD ? Just dying to know where those savings are made, seeing as the frames looks pretty much the same, bar a slightly bigger cut out for the rear wheel (no doubt to be able to run 25c tyres) but would have thought that would make it 'less' aero.. Hmmmm

The new color scheme is very sharp, nothing fancy - reminds me of the 2011 S3.  That bar is interesting and reminiscent of what 3t is coming out with I believe from an earlier in the year cyclingnews.com feature on David Millar's current S3.

 New fork. Thicker and with a curve.

Nice..very nice!

Just to clarify, the new S5 full bike has a 21.3 watt saving out-of-the-box versus the current S5 VWD full bike. Some of that is wheel, some handlebar. The feedback we've heard from shops and riders alike is that they want to see faster wheels on our spec bike. And yes, plenty of clearance for 25c tires.

Aero savings are always welcomed, but one of the best features will certainly be the added front-end stiffness due to the tapered headtube and revamped fork... very cool!

That's a little misleading then. Can't understand why anyone buying an aero bike would put in standard wheels ! So other than the bars, is there any wattage saving in the frameset alone ??

That savings due to different wheels is very "Trek like" in terms of marketing instead of technology. It looks like the real technical improvements are the better wheel clearance and improved stiffness. But where are the details about the "updated RCA"?

We will have full product information available on our site for both the S5 and RCA once the bikes are ready to ship to your local shop in October. I think you'll find that we are, as always, very upfront & clear with our aero, stiffness, and weight claims in that info. In terms of the S5: the aero savings of the full bike are just a small piece of the total advancements made on the bike. Slowtwitch just really likes to call out aero first.

Thanks for the clarification, David. I'm happy to know that Cervelo remains an engineering first company, unlike many competitors.

I do like the look of the new S5...very "clean" looking. Simple graphics, but the color scheme is carried across the bike...wheels, saddle, tape, graphics...very sharply dressed in a tuxedo kind of way :)

I'll wait for the specs to come out, but it does look like a revision vs. a "new" design. I see there are Conti tires there....that bodes well for taller tires, but I'd still like to see room for GP4000s 700x25's for us bigger guys and folks looking for the advantages of wider tires. No, I'd not be looking for 28's on an S-series frame, but Conti 25's would be nice.

Not quite enough to get me off my S2 yet (though the compliance of the S3 with only a minimal aero penalty vs. the S5 makes that frame a bit more tempting, but that's only because of my current riding style and needs).... but of course, if this Clyde butt were given an S5, I wouldn't complain and I'd ride it like I stole it :)

Love the color scheme and the bigger cutout. I wonder if that aero handlebar will be available as a separate purchase. That handlebar will make our out-front GPS mounts useless though :)

 I couldn't help but notice that there seems to be a missing UCI sticker on the S5.  Are the bars UCI legal and the sticker is just somewhere out of site?

Wohoo .. rock'n roll for the road!

Tapered steering tube for more stiffness, more aero for more and longer speed, beautiful shaped fork and optimized frame, enough clearance for GP 4000s II on any race wheel set. If it has the same geometry as the current S5 a 56cm frame would replace my 58cm Soloist Carbon. Can't wait for the next season with another 20 Watts of savings for a 191cm rider. Yipiiee and thanx in advance for the fun .. oSo >>
