3D30 - Super-compatible UBB30 technology
The 3D30 uses ROTOR’s ultra-rigid and super-compatible UBB30 technology (developed for the 3D+), offering an “indestructible” upgrade opportunity for almost all bikes on the market – whether they were designed for 30mm cranks or not.
Cold forged, trinity drilled
The 3D30's cold forged, trinity drilled arms and aluminium UBB30 axle ensure serious rigidity and performance to face anything you can throw at it, while saving weight in regards to the majority of 30mm cranksets. UBB30 axle - Groundbreaking concept, 100% compatible
The 3D30’s axle technology comes from our UBB concept, which encompasses all bottom bracket standards on the market. This allows for surprising and unexpected new options for upgrading bikes of any BB type: our groundbreaking UBB30 axle concept is 100% compatible with BSA (68 & 73), ITA, BB86, BBB89, BB92, BB30, BB386 evo and BBRight bikes. 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 Brackets - It works with everything!
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.
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. Twin Leg Concept
TLC or Twin Leg Concept creates the best, most balanced cranksets.
