      ROTOR crank REX 2.1 XC1 MTB 1 times

      To meet the growing demand for separate MTB cranks comply to Rotor decided to own MTB product line. The successor of the 3D cranks are now called REX.
      The new REX cranks not only look, but also through technical values. Using the "Trinity Drilling System", the material is removed from the center, "neutral axle" of the crank arm at the REX cranks. This material contributes only to the least extent to sustainability of a component and can be omitted without any negative consequences. The necessary stiffness and stability is achieved with lightweight construction oversized outer diameter!
      The crank is provided with a shaft of 30 mm outer diameter (UBB30) and guarantees maximum compatibility with many frames. The arms are available in various lengths, 170, 172.5 and 175 mm. As material extra light and durable 7050 aluminum now used.

      Light, stiff and extremely chic.
