Lighter and stiffer than ultra high end carbon cranks
As the lightest crank in the road line, the NEW 3D+ takes advantage of a new 7055 alloy and an entirely redesigned structure based on TDS technology to reduce weight while maintaining rigidity. The 30mm axle with UBB30 technology makes 3D+ compatible with almost all bikes, whether they are designed for 30mm axles or not.
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.
Micro Adjust Spider
More positions to suit every rider´s needs
The new Micro Adjust Spider (MAS), offers more positions to suit every rider’s needs. Our new advanced MAS spider has an alternative bolt hole placement allowing for intermediate positions between existing OCP (Optimum Chainring Position) of the Q-Ring. A standard crank in combination with the OCP of the Q-Rings, allows approximately 5 degrees of adjustment.
The MAS spider when used with Q-Rings offers half positions giving approximately 2,5 degrees. This means that you can micro adjust the position of your Q rings, to suit your riding style.
