114mm Alloy based Cotterless Cranks - supplied as a pair. These Alloy variations are significantly stronger and lighter than the steel versions. Each features Qu-Ax branding. Please ensure you connect the 'Right' Pedal to the 'Right' crank (and so on) to avoid cross-threading. These cranks are compatible with the Indy Trainer range and the Qu-Ax Luxus series.
