Your bike is more than just a tool for training; it's an accessory to your lifestyle. You've engineered your life to accommodate your riding, it seems reasonable to expect the same of your bike components. The 3D+ 110 is a work of engineering founded upon the principles of lightweight and rigid. Crank arms CNC-machined in Spain from aeronautic-grade 7055 aluminium are combined with proprietary technologies to yield cranks with an exceptional stiffness to weight ratio that can handle the dizzying wattage that you'll stomp out on the 3D+. Together with ROTOR's Universal Bottom Bracket (UBB) system, the 3D+ compact crank offers a performance upgrade opportunity for almost all bikes on the market.
