According to their whitepaper the difference between the new S5 with a std. stem/ their old aero handlebars without cables and the same setup with cables is 13 grams. (Bottom of page 17). The drag savings between the old bike and the new bike out of the box (I assume with properly trimmed cables) at 0 deg. is negligible. The difference over the yaw range appears to be 42g.
Hmmm...since the new bike doesn't have ANY accomodations for external cables, nor a front mounted rim brake (with resulting exposed cable), I'm wondering if they're just talking about the exposed cables between the handlebar and their "standard stem adapter"? That would be some incredibly short runs, especially as compared to the previous gen S5.
That is my understanding as well. That's a case where a photograph or two of the test setup would be helpful to put the result into context.
Most definitely. It'll be interesting to see the rim version of the new S3, and see how well they integrated the cable housing on that particular model. So far I've only seen pics of the disc S3...anybody see the rim version?
I'll be really surprised if the brakes and associated cables aren't very similar to the old S3/S5.
I'd like to add that for all the CFD graphs showing the V better, it doesn't seem any better at 0 yaw in their own wind tunnel graphs. Is there any evidence to suggest that this would only show itself w/ rider on tunnel testing?
I'm going to make one other comment, but before I do I would like to state that my eyeball wind tunnel is no good...never has been...and probably never will be. But does anyone else think the front of the fork's surface directly above the tire seems a bit blunt? At least in comparison to other disc bike shapes at that spot i.e. Venge, Madone (disc), SuperSix?
