Product Description

ROTOR believes that functionality and realiability - not fashion - best define material selection when it comes to crafting 1x and 2x REX 1 cranks. Crank arms CNC - machined from aeronautic-grade 7055 aluminiun are combined with proprietary technologies to yield cranks with and exceptional stiffness-to-weight ratio that can handle a thrashing off road. Together with ROTOR´s Universal Bottom Bracket (UBB) system, ROTOR cranks offer a performance upgrade opportunity for almost all mountain bikes on the market.
