ROTOR developed the 3D road crank to be extremely stiff in order to meet the demands of Thor Hushovd and the sprinters of Cervelo Test Team. It also needed to be lightweight enough to satisfy the needs of Carlos Sastre and the climbers as well. ROTOR utilizes a special manufacturing process named the “Trinity Drilling System. An extruded aluminum bar is intricately CNC machined with three drilled holes through the length of the crank. The result is a unique triple hollow crank arm that enables Rotor’s engineers to remove the excess aluminum in the core while still maintaining the structural strength of the crank. Road standard double (130mm bolt-circle diameter) with either a 24mm or 30mm steel or 24mm or 30mm titanium spindle. ROTOR cranks require ROTOR Bottom Brackets. Chainrings and Bottom Bracket are not included.
KEY FEATURES:
- The UBB (Universal Bottom Brackets) system 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
- Utilizes Rotor's Trinity Drilling System (TDS) technology to reduce weight but maintain rigidity
- 100% CNC machined, T6 7075
- Ultra stiff 24mm Aluminum UBB axle; compatible with BSA, ITA, BB86, BB30, BB30 PF, BBRight and BB386 Evo frames
