Did you get geometry details? Or going on faith?

From this post on page 3:
55 cm, 691g.

So if we assume 50 grams for paint on the larger frame relative to the smaller (the early photo was unpainted), that's a 4.2% increase in mass for a 1.8% increase in frame size, which extrapolates to 580 grams for a 51-cm frame.

As I guessed before, I suspect they're aggressively scaling weight with frame size to keep a constant stiffness, rather than allowing the small frames to be over-stiff, as is more typical.

AX components are "lightness over everything else."

I know it's a cultural thing to have a knee jerk reaction that more of something better\stronger. But you of all people, with such a noted scienterrific mindset, dj?
Anyhow- Fact is that f.i. Ax seatposts are all rated for MTB and road, their cranks and this
particular frame have a 110kg rider limit. Other überlight offerings from the
fatherland such as the Schmolke TLO bars are actually stronger than the slightly
heavier models in their range, etc, etc.
Ax is not low weight at any cost by any means. Did you watch the LeMans 24hr race?
Those Audis have a lot of Ax carbon on board...


I'm not sure what you mean by this. The name itself, I understand, means "lightness over all". Obviously weight is the top priority with these components. I didn't say they were recklessly light, but clearly if you have more material, you can usually make something stronger and more durable.

Mass + Speed = Energy
In practice lighter is often stronger with moving objects such as bikes.
Quality of manufacturing and engineering, care and skill
in the application of sound material knowledge, higher quality materials etc, etc...
-will always factor more than sheer quantity.

Re the name- 'ax' is for Axel Schnura.

"Today's stage is over the pave. I'd better tell the mechanic to mount the AX-Lightness gear...."

Could happen, I suppose.

I totally have the AX bug...I'm loading up on components. The frame looks nice but it's coming out a little too late for me.

Will be interesting to see it perform against the new Storck 0.6, which has internal Di2 cable routing.
(Weight I think is going to be around 620g)

(spoke to the guys at Poshbikes recently, he's just made a wallet busting bike which came out at a final weight of 3.75 kg)

The Fascenario 0.6 also has integrated brakes! Looks quite cool, I think... :D

looks like it'd be a pain in the ass to change the pads

In my dreams I might take the Fascenario 0.6 over the AX frame. They need to fix fork break to the same mechanism as the back and loose that silly cable coming out the side of the fork. I'm sure there is a way to route the cable down the inside of the fork.

The AX frame a big achievment for AX, and if priced below Cervelo's R5 is might be a winner.

Will have mine in August. :-)

The brakepads are in fact quite easy to change. The fat stays are cool IMO and not just copycatting design from others. If designed correctly, the comfort will be just as good as frames with pencil thin stays. There's a bit more to it than that...
Storck will come out with a new frame next year that has a lot more compliance than a Roubaix SL2, and that frame has "normal" size stays.
