Your bike is more than just a tool for training; it's an accessory to your lifestyle. You've engineered your life to accommodate your riding, it seems reasonabe to expect the same of your bike components. The 3D+ 110 is a work of engineering founded upon the principles of lightweight and rigid. Crank arms CNC-machined in Spain from aeronautic-grade 7055 aluminum are combined with proprietary technologies to yield cranks with an exceptional stiffness to weight ratio that can handle the dizzying wattage that you'll stomp out on the 3D+. Together with ROTOR's Universal Bottom Bracket (UBB) system, the 3D+ compact crank offers a performance upgrade opportunity for almost all bikes on the market.

“MAS” stands for Micro Adjust Spider and means “more” in Spanish. That’s what this technology is all about: more adjustability to further optimize your Q-Rings. Additional bolt holes allow for intermediate positions between a Q-Ring’s existing Optimum Chainring Positions (OCP). A standard crank and Q-Ring combination offers approximately 5 degrees of OCP adjustment. MAS together with Q-Rings offer half positions of approximately 2.5 degrees of OCP adjustment. This means you can micro adjust the orientation of your Q-Rings to fine-tune your pedal performance.
