These crankarms are CNC machined in-house from ultra-strong 2024 American alloy. This allowed to remove a lot of material for an elegant design, while retaining excellent strength and stiffness When Paul suggested to bring back the classic 100% Pure Paul cranks, but with a 3-bolt Direct Mount chainring spline and integrated crank extractor bolts, his team was excited. When he suggested a J.I.S square taper for the bottom bracket... really? It's 2025.
