TRINITY DRILLING SYSTEM - Bombproof design and reliability
ROTOR's bombproof trinity drilled crank arms resist bending and twisting forces better than classic hollow tube crank designs can. ROTOR’s crank arms are stiffer than the competitions forged products due to our Trinity Drilling System. This process drills three full-depth holes from axle to pedal, leaving behind a boxtrellised structure (similar to box bridges). This gives our crank arms superior rigidity and an exceptional stiffness-to-weight ratio.
UNIVERSAL BOTTOM BRACKETSIt works with everything!
The UBB (Universal Bottom Brackets) system is not a standard; It’s all standards. It allows installation of almost any 30mm axle crank from ROTOR on the bike you have, regardless of its BB type. ROTOR’s “UBB” super-standard encompasses all BB standards.
Solutions. That’s probably the best word to describe ROTOR’s design philosophy. We identify performance problems and set out to solve them, resulting in improved & optimized products.
