This is a direct-mount crank spider engineered by ROTOR for use with many of their modular crank systems (including ALDHU, VEGAST, 2INpower, and INpower). It’s designed to accommodate both 1x and 2x chainring setups using the 110 mm × 4-bolt interface. The 'MAS' designation stands for Micro Adjust Spider, which provides additional chainring mounting holes so you can fine-tune the Optimum Chainring Position (OCP) when used with Q-RINGS — giving around half-step (~2.5°) positioning adjustments for better pedaling efficiency.
