The Stemma is a unique stem from Wilier that aims to clean up the front end of your bike while offering excellent stiffness at a low weight. While Wilier has offered the intergraded Alabarda for some time offering excellent aerodynamics and clean cable routing, options for bar width/stem length were limited as well as the ability to rotate the bar to your preferred angle of choice. The Stemma, when paired with the Barra, offer the advantages of an integrated setup, namely stiffness, aerodynamics, and clean routing, with the adjustability to dial in your fit.

Constructed of carbon fiber, the stem comes in at a respectable weight that won’t weigh you down in your quest to build a lightweight bike. And while the Stemma is offered in the same length options as the Alabarda, the ability to pair it with different width Barras bars gives it more flexibility when it comes to dialing in the fit.

The main feature that stands out on the Stemma and perhaps the biggest reason you'll want it is its ability to run the housing internally which helps not only tidy up the looks at the front of your bike but also reduces drag by hiding the housing.
