Professional road racers have been constrained for years by a minimum bike weight limit of 6.8kg/14.99lb. Dressed in Campagnolo Super Record and HED Stinger 3 tubulars, Wilier Triestina's new Zero.6 is a full kilo less than UCI legal.
Wilier's Zero.6 frameset is named after its weight in kilos: 0.68kg. (The Italians round down, evidently.)
It wasn't too long ago that sub-900g was the target for superlight climbing bikes. Well, after Wilier and others got under that, and then under 800g, sub-700g became the quest.
WIlier achieved the new weight target with carbon from Mitsubishi Japan.
Aside from the eyebrow-raising weight, there are some neat details on the frame, like dropouts made in monocoque with the rest of the rear triangle and internal rear derailleur cable routing that pokes out of the back of the derailleur hanger.
Wilier sells the Zero.6 as a frameset in the US and as a variety of high-zoot builds elsewhere.
I got a hold of this Super Record build with HED's 1,189g Stinger 3 wheels, Continental Sprinter tubulars and Ritchey SuperLogic cockpit, and put it on my Feedback Sports scale: 5.8kg / 13lb.
At 185lb / 84kg myself, I am an ironic rider to perch atop such a machine. However, I make for a decent tester of light bikes, I think, because I can suss out what flexes and what doesn't.
In the first few rides, the rear end of the bike felt surprisingly stiff, but the front end of the bike moved under hard torque. It's hard to say whether this was the Superlogic bar and stems flexing, the steerer tube or a combination thereof, but the end result was a far cry from my Shimano PRO cockpit on an older Scott Foil.
I'll be riding this bike more — including with a Campagnolo Shamal Mille that comes on one of the stock builds — and reporting back with a full review soon.
