Argon 18 has been rather busy, bringing about new bikes for all the hot pavement categories -adventure road, aero road and triathlon- and equipping them with some new components from TRP and, from the looks of it, Shimano.
The biggest news is the all-new Nitrogen aero road bike, which incorporates all-new TRP linear pull road brakes. The frame utilizes many of their existing technologies and designs, including their HDS (Horizontal Dual System), which slices an imaginary line from the top of the head tube back to the rear dropout. Everything below that line is stiff and oversized, above it things are thinner and more compliant. The idea, now common, is to enhance power transfer without sacrificing comfort.
It also uses their progressive sizing and integrated head tube spacers, albeit with an aero shape, to accommodate a wider variety of rider shapes and sizes. The bottom bracket gets a 75mm drop to put the rider’s center of gravity low and keeps the head tube height low for a stiffer front end and snappy handling. It’s all assembled with a 7003 HM nano-tech carbon, which brings the medium painted frame weight to just 960g. Hardware (+60g) and Di2 bits (+23g) add a little more. Fork weight is claimed at 366g when cut to fit a size medium frame.
To get aero, they used smart tube shapes, hidden brakes and custom seat tube…
UPDATED…with the real deal on that “new” Shimano Di2.
Slender headtube and fork legs slice through the air and trailing edges reduce turbulence. Their 3D pressfit head tube extenders provide extra height without giving up stiffness. On most of their bikes, they’re much rounder, but here they get a tear drop shape.
Various heights are offered.
Down below, the huge bottom bracket surrounds a PF86 shell and mates to asymmetric, oversized chainstays.
Besides the very different build from the Eurobike display model, it appears to out what could be a next generation Dura-Ace Di2 (thanks to Michael for the tip!).
Two things jump out: A more angular design to the rear derailleur with a slightly smaller tail end and harder lines to the front “P” knuckle. The front derailleur looks much, much more compact with a more distinct crease and indent at the front of the outer cage.
The levers get a more pronounced point at the top of the hoods and very angular button shapes. The front button that sits against the brake pad seems to move most of it’s surface area lower, creating a more cohesive button area. Altogether, the group looks a little leaner and meaner.
So, is this the next gen Di2? Or just renderings to fill the website? (…) a leaner and meaner seems like the right progression for a group that’s seen a couple years of action.
