IB13: Argon 18 Produces Gallium Pro, Drops 160g in Frame Alone

What do you get when you take 160g out of the already light Argon 18 Gallium? You get the impressively light Gallium Pro, now with a 790g frame weight. By changing the carbon layup and thining out the chain stays Argon we able to lighten up the frame while still keeping the bike stiff and fast like the original. Even with a super light frame, Argon 18 is still able to offer their 3D headtube system to tailor the headtube length to your fit. Just what is the 3D headtube system? Think of it as three different fits built into one single bike.

Rather than offer 3 different geometries for the Gallium Pro, Argon offers them all in a transforming design. Users can tailor the effective head tube height to their needs by changing out the 3D spacer that add 15 or 25mm to the total height of the head tube. Argon claims this design not only offers more fit options, but preserves stiffness at the handlebar by 5% at 15mm and 11% at 25mm compared to just headset spacers. Inside the 3D system is a tapered steerer tube for the GA31 Fork.

The stays have been thinned drastically on the Pro as part of the HDS or Horizontal Dual System – essentially marketing speak for drawing a diagonal line from the head tube to the rear dropout and thinking of the bike in terms of the upper half built for comfort and the bottom half built for power and speed.

As such, the frame uses a BB86 bottom bracket with a downtube that’s almost as wide as the BB shell and squared chainstays for maximum power transfer. The Gallium Pro is set up to run mechanical or electronic drivetrains and requires no additional parts to switch.

The end result is shown with a small frame, full Dura Ace build including the wheels at 14.18 lbs, or 6.43kg.

Finally, A headset spacer you can see from space.

They vetoed calling the headset “the turtleneck”?

One word: “elegant”

Why are crabon fibre road bikes so boring? What a losing market.

Why do you say boring? Perhaps it’s the unimaginative demands that most riders make now days of frames dominated by black paint with a dash of red? Personally I think it’s a rather elegant frame. Through on a set of aero wheels and get rid of the Shimano and I bet it looks hot . . . just saying.

Goathead +1 Should say Crapbon

There may be one or two truly innovative road models each year, but not much more than that. Mostly, it’s just lighter, stiffer, but aerodynamic innovations are slowly moving to the front. Your Shimano bashing is incredibly misguided. SRAM is getting better nowadays, and Campagnolo is now better than mediocre, but you really should try 9000/6800 for a breath of fresh air.

If only Cervelo had thought of a similar concept for their R-series. Wait . . . now my head hurts . . .

Needs disk brakes and through axles. Everything else is obsolete.

Argh - 10/04/13 - 3:12am

@shafty what aerodynamics do you mean? current frames and wheels are all aerodynamic at their max (UCI legal).

Norman - 10/04/13 - 4:01am

Which part of the ‘Horizontal Dual System’ is horizontal? If I want a stiff frame, I will get one. If I want a frame built for comfort; I can get one.

Why would you want a super stiff lower half with a top half that floats around like a bowl of custard?
