|Our famous 3D crank is now renewed to stay as a benchmark. It’s structure was lightened by means of triple drilling technology and “Closed Clamp Concept” technology makes the crank lighter and stiff. BCD 130 (aero) and Track BCD 144 options available.|
The 3D continues to lead the 24mm crankset market in terms of technology, performance and rigidity. It is ROTOR’s most lauded crankset, having helped athletes that rode it to win three grand tour jerseys and no less than 15 UCI elite world champion titles.
Trinity Drilling System
Its bombproof trinity drilled crank arms resist bending and twisting forces better than classic hollow tube crank designs can, and feature an intelligent clamping system; the closed clamp concept (CCC). A CCC comes out of our CNC machines in its closed position, being placed under strain only briefly during installation when the clamp is forced open and on tightening the bolt in returning to its nominal low-strain closed shape. All other systems on the market are placed under strain by installation.
Universal Bottom Brackets
The UBB (Universal Bottom Brackets) system is not a standard; It’s all standards. It allows installation of almost any 30 or 24mm axle crank from ROTOR on the bike you have, regardless of its BB type. ROTOR’s “UBB” super-standard encompasses all BB standards.
