The Crankset without Spider from Hope has been developed over many years, designed using the latest FEA (Finite Element Analysis) tools and endured extensive multi discipline field testing. The outcome is what you see before you, a Forged and CNC machined 7075 series aluminium alloy set of crank arms with a 30mm oversized axle and a unique expanding spline/arm interface system. The versatile spline mount for chainrings and spiders allows you to run either a conventional chainring (single or double) or a direct mounting chainring which allows you to save weight whilst also saving weight and giving a quieter drivetrain with less drag (sold separately). These cranks are available in 175mm. 170mm and 165mm with 68/73mm axle options. Black only.
