At the heart of the Allez Sprint is our D'Aluisio Smartweld Technology, which strategically places more welding material where it's needed, resulting in an aluminum bike that's more compliant and considerably stiffer. How stiff, exactly? It's the stiffest alloy bike we've ever tested, let alone made.
Drawing inspiration from the Rider-First Engineered™ Tarmac, this frame also has a unique down tube, bottom bracket shell, and head tube, plus fork sizes that correspond to frame size. This ensures uniform performance across the entire size run.
To make sure that every single watt you produce gets transferred to the road, we gave it short chainstays that create an extremely stiff and rigid rear triangle. But it goes beyond just pure rigidity, as the hydroformed tube shapes have also been aerodynamically optimized to slice through the wind, while also providing tons of built-in compliance.
