The Cento1SR's tripartite composition is a properly Dantean story of threes. Wilier uses three distinct types of carbon fiber in different areas of the frame in order to meet the exacting demands of three criteria: stiffness, weight, and comfort. The drive spine and joints most integral to power transfer are built with Mitsubishi's 60t, a material with such high tensile strength that we've referred to it elsewhere as the synthetic equivalent of Superman's hair. We stand by that bit of artistic license, though we're also compelled to note that such stiff power-transferring efficiency does come at the cost of elasticity and vertical compliance. It also makes 60t as rare (and expensive) as kryptonite. Other areas of the frame are built with lower modulus T800H and T700SC carbon fibers, which add a vibration damping and compliance to 60t's unforgiving ride and bring the cost of production down without sacrificing a single watt of drive spine efficiency.

Though the construction is impressive, few elements define Wilier framesets in cycling's popular imagination more than handling, which is in turn defined by the frame's geometry. The Cento1SR's tight wheelbase and tapered head tube net apparently contradictory properties. While the former contributes to a race-ready, jumpy responsiveness, the head tube height and front end shape bring an element of stability and comfort across sweeping descents and long base miles. Much of this carries over into the current model; however, Wilier also incorporates designs from its other top-offerings (the featherweight Zero.7 and the aerodynamic Twin Blade) in order to capitalize on those qualities and make the CentoSR1 its most balanced all-purpose frameset.

One design feature that's native to the Cento1Sr is the asymmetric chainstays, which serve two primary functions. First, they address the differing load demands on the drive and non-drive sides, balancing a beefed-up, moto-inspired drive-side stay with a supportive, lighter non-drive stay. Second, the asymmetrical design reduces chain slap. Admitting that we may actually like this feature more than the increased efficiency isn't an overstatement, because every time we hear the sound of nickel-plated steel smacking across high-modulus carbon while riding across stones or train tracks, our hearts break a little. We're fairly certain that, with the exception of the pros who abuse their gear to the point of criminal culpability, every other cyclist feels the same, and this is yet one more detail that demonstrates Wilier's obsessively passionate design ethos.

The list of technology adopted from Wilier's other frames results in one of the most effective power delivery systems on the market: the combination of those chainstays, the 60t carbon, and the BB386 EVO bottom bracket. Developed by Wilier, FSA, and BH, the BB386 EVO is the product of yet another tripartite coalition. It's got a titanic 86.5mm wide shell and 46mm diameter, which increases rigidity by a claimed 30% across the bottom bracket junction by allowing Wilier to expand the seat and down tubes by some 20mm. This greater tube diameter improves power transfer and requires less material (and less weight) to maintain structural integrity. Altogether, Wilier credits the BB386 EVO standard with increasing overall torsional rigidity by 133% and rear triangle stiffness by around 115%.

As with the previous model, the Cento1SR is finished with a host of returning features including a stiff, multifunctional 3D derailleur hanger, a 3D integrated cable routing plate under the bottom bracket shell, an integrated adjuster plate for your internal cable routing, and an integrated fork for a more aerodynamic front end that handles with the classic smoothness we expect from Wilier. The internal routing is compatible with all mechanical drivetrains and both Campagnolo EPS and Shimano Di2.
