The Rotor 3D plus MTB Double crank is so stiff and spins so smoothly that you'll be thinking about buying bigger chainrings for your bike. Rotor's top-of-the-line stiffness comes at a minimal weight, compliments of a unique drilling process, which removes material from the inside of the crank arm. The 30mm spindle is optimized for any press-fit 30 frame. However, simply pair this crank with Rotor's BSA30 bottom bracket to experience the stiffness of a BB30 with a threaded, English bottom bracket shell. Customize your 3D plus with your choice of chain ring sizes in either traditional round rings or Rotor's energy saving Q-rings (sold separately).
