ROTOR offers their MAS spider as an option with select ROTOR power meters – such as the 2INpower MAS power meter. MAS stands for Micro Adjust Spider. The ROTOR MAS spider allows you to fine-tune your Q-Ring position to better suit your needs and pedaling style. ROTOR calls this the Optimum Chainring Position (OCP).

For example, using a standard spider and ROTOR Q-Ring, you typically have approximately 5 degrees of adjustment. The MAS spider has additional bolt hole options, effectively giving you half positions or approximately 2.5 degrees of adjustment.

In addition, there is no additional weight penalty when using the MAS spider.
