At the very top level of racing, every millimetre of advantage you gain by the bottom of the hill turns into metres by the time you cross the line. The 2024 Speedco EVO builds that idea into the frame: more aerodynamic tubing, and a beefy down tube that connects past the bottom bracket straight into the chainstays.

That down tube and bottom bracket interface is laboratory proven to stiffen the whole bottom end, which matters on a bike that takes a standing gate start through light gearing and long cranks. The EVO is fully committed to disc, with a flat mount calliper on the inner axle block and the hose routed inside the chainstay, and this Pro XXL runs a 21.0 inch top tube in Toray carbon fibre at 1384g.
