The ROTOR 2INpower MTB Crankset Power Meter takes ROTOR’s renowned 2INpower technology to the dirt with a version designed specifically for off-road use. The 2INpower makes several improvements over the previous generation INpower. Features such as independent left/right power, Bluetooth SMART and rechargeable li-ion battery technology are all new with the 2INpower ROTOR MTB.
The ROTOR 2INpower MTB features ROTOR’s 30 mm UBB (Universal Bottom Bracket) design which make the power meter compatible with almost all standard frames when used with the correct spacers. In addition, when used with a Q-Ring, ROTOR’s OCP (Optimum Chainring Position) technology allows you to identify your OCP in order to fine-tune your Q-Rings for optimized pedaling performance and efficiency.
