Aerospace Aluminum Alloy 7075 offers excellent physical properties for building parts such as Q-Rings and REX 3 and 3D24 cranks.
Rotor CNC cranks are stiffer than the competitors' cranksets thanks to the Trinity Drilling System (TDS). In this procedure, three full holes are drilled from the bottom bracket to the pedal. This creates a box-like grid, similar to a box girder bridge. As a result, the cranks are extremely stiff and still lose weight, whereby an outstanding relationship between stiffness and weight is achieved.
The UBB System (Universal Bottom Bracket) allows Rotor to use both 24mm and 30mm axle diameter, making it compatible with almost all frames on the market.
