So Dogma F10 shaved a few grams and now flexes...

I don't think those flex numbers are too bad, what I'm more surprised about is the aero - correct me if I'm wrong, but the Dogma F10 is more aero (or at least in the same ball park) as the Trek Madone 9, Venge Vias?
I write the weightweenies blog, hope you like it :)

Not having the stiffer headtube in the world is not a bad thing. I believe the SL4 is the has the the best head tube, on paper, of bikes that I've ridden but that did not translate into my favorite bike descending.

As for the drag, I believe 202g was also reported for the Bias and Madone but if I'm not sure it's as comparable if those results aren't coming from the same tunnel with same testing procedures. Just looking at them, I'd be very surprised if the F10 was equal.

For me more than going downhill, front stiffness is key when you lift from the saddle and start balancing the bike left and right, that's where I find responsiveness.

Tour magazine's 2016 shootout shows venge vias and madone at 204W Felt AR 205W and Canyon Aeroad at 208W but tbh, I am still doubtful of their numbers. They only produce tables and written paragraphs. I don't remember seeing raw lab data.

And this is where my C59 and C60 have both been lovely. They're the best feeling climbers I've owned - and both are more planted on the way back down. The Tarmac was lively all over - I just wish it was less so on the way down. Subjectively, I choose to attribute that to the class leading (or close to it) head tube stiffness.

I would take the Diamante anytime even if the numbers were not us good.

How do these numbers relate to your riding. Say you apply xx NM to the cranks and the bottom bracket sways 1.06mm instead of 1.00mm....what does that actually mean for your ride ?

For every 5W you save in aero drag, you will save a second if you manage to ride at same aero position for an hour at a speed of 40km/h

If the F8 is a reference I would not worry one second about the "flex" of the F10.

Me too, such a gorgeous bike, especially in the blue/fluoro

One of the reason i bought C60. No flex at all while climbing. When u climb on C60 the only flex u feel , is flex from ur body :)

Today i had climb where average is 9.5% which was long 8.5 km where i was able to feel that again :)

BTW, when i tested the Dogma F8, i did not feel that stiff for climbs as C60

Same here. Basso Diamante is really made in Italy (not just painted there) as well!!!!
