Wilier Zero.7 Road Bike Frame $4,999.00
As good as it gets.
Italian exotics have always tapped deeply into our senses. Seriously, who didn’t have a 308 GTS or a Countach on their wall as a youngster? And if you grew up on two wheels, Bimota and Aprilia offerings were just as lust worthy. The Wilier Zero.7 Road Bike Frame carries on this tradition, though its matte finish is understated in comparison to the sort of flashiness we’re used to from Italian designers. It looks more like a high tech project bike, which isn’t far from the truth. A close look will reveal some, but not all of the structural details that make the Zero.7 such an astounding performer on the road.
The massive down tube and seat tube juncture at the bottom bracket shell begs for attention. The beefiness here is a byproduct of the BB386 EVO bottom bracket system. Where a typical road bottom bracket shell (BB30 included) is 68mm wide, BB386 EVO is a full 18.5mm wider. The down and seat tubes intersect the shell at greater diameter, giving it greater surface area as a whole. The result is a lighter, stiffer frame with no power-robbing flex.
Before you roll your eyes at yet another BB standard, know this: BB386 can be used with any crankset on the market except for BB30. The shell dimensions of 46mm ID and 86.5mm width might sound familiar. A Pressfit30 shell uses the same 46mm ID. This means that Wilier's BB386 uses an existing, easy-to-source bearing assembly. The 86.5mm width is the same as a standard BB86 pressfit shell. This ensures compatibility with any typical external bearing crankset using either a 24 or 30mm spindle.
What you can't see is that Wilier employs a Special Elastic Infiltrated (SEI) film within the composite lay-up. While this technology has been used in the aeronautical and automotive industry, Wilier has pioneered its use in racing bicycles.
The SEI Film enables three things: 1) It increases impact resistance by 35% over a laminate composed of carbon fiber alone. 2) It increases inter-laminar shear strength by 18%. This is significant when the flame is flexed, particularly in acute flexure (read: crash into something). The film acts to damp the shear movement and retain the adhesion between layers, preserving the strength of the frame. 3) It increases flexing strength by 12%. This translates to a stiffer laminate with better stress-strain response, and you'll have a bike frame with more resistance to cracking. A very tangible benefit is that the SEI film also increases the vibration damping of the frame. You'll be more comfortable over rough roads on the Zero.7.
The SEI film also reduces the need for some of the intermediate modulus carbon that would typically be used to blend with the ultra-stiff 60 ton high modulus material. This reduction in material means a lighter weight bike. The Zero.7 gets Mistubishi's MR60H carbon in the areas of highest stress. With its incredible strength, less can be used. And again, less material equals a lighter more responsive bike. Wilier specs a resin system that includes zinc oxide nanospheres. These tiny particles serve as structural filler in the void space between the carbon fibers, saving weight and increasing strength.
The 1-1/8" to 1-1/4" tapered head tube is reminiscent of that found on the Cento1. Similarly, it's rounded on top and squared off on the bottom. The squared head tube mates to a squared fork crown, with the goal of providing outstanding steering precision. Whether descending a mountain at speed or sprinting out of the final corner of a criterium, the Zero.7 is stable and easy to keep on a line.
The Wilier Zero.7 Road Bike Frame is available in six sizes from X-Small to XX-Large, and in the colors Black/red and Giallo Lampre.

Hats off to wilier's engineers
- Familiarity: I've put it through the wringer
I had the privilege of spending a solid month and several hundred miles on one of these frames, and it was wonderful. While it was indeed a responsive, agile machine, thanks to its low weight and stiff 386 bottom bracket, what truly blew me away was how remarkably smooth and comfortable it was - and at the time, I was riding a wheelset that was known to be particularly harsh. The feathery weight, geometry and handling characteristics would make this a fine race machine, and it could even be set up properly for criteriums, however, the silky ride quality and planted demeanor encouraged me to just spin for miles. This would be one of my top three recommendations for a rider looking for a truly balanced frame. Are there lighter, stiffer bikes for racing? Yes. Are there smoother, more relaxed bikes for long distances? Yes. Are there bikes that can do both? Maybe, but very, very few as well as this one.

I purchased this bike on a recommendation. I was lucky enough to fly to Utah when they were putting it together for a perfect fit. I've rode Trek Madone, Pinarello Prince and a Cervelo S3. This bike blows all three out of the water. I have Campi Super Record with Zipp 303's on the bike right now and it feels like a dream.
