Wilier uses a 60 ton carbon fiber in the 2015 Zero. 7's construction. And while it's nothing new for the bike industry to use higher modulus carbon to reduce weight and spike the strength ratio, the actual comfort factor drops significantly. High modulus carbon doesn't absorb as much road vibration, leaving your bones rattling. Wilier instead looked at the carbon fiber itself and worked the perfect go around. The result is a frame that weighs 19% less than its 2014 predecessor. Rather than wrapping a bladder in pure carbon, Wilier incorporates both a Zinc Oxide nanoparticle epoxy resin ZnO and SEI, a Special Elastic Infiltrated Film, into its high modulus designs. By using an internal inflating bladder, the material is compacted in the mold from both the exterior as well as the interior. This not only creates a smooth surface with uniform wall thickness, it also eliminates any hotspots of resin buildup. Both the ZnO and SEI work to reduce vibration as well as increase impact resistance. So now you have the best carbon imbued with two near magic compounds. How could the outcome be anything other than podium worthy' If the innate stiffness of the 60 ton carbon isn't enough, Wilier redesigned the head tube into an hourglass shape to further increase front end stiffness. Additionally, the shape provides more aerodynamic gains, and anything that makes us go faster is a plus in our books. To finish the frame, Wilier uses its integrated fork, a work of art in its own right. The bottom bracket has also received added attention and now houses the BB386 EVO, with 30% more stiffness over a 68 millimeter bottom bracket. Please note that this frame is not compatible with Campagnolo EPS groupsets.
