Rotor 2INpower SL Crankset More data, less weight Building off of the original 2INpower crankset, the Rotor 2INpower SL shaves weight, while maintaining the performance and modular design that Rotor is known for, with an ultra-precise, integrated dual-sided power meter for accurate power readings. The INpower SL Crankset is the lightest dual-sided power meter on the market, machined from 7075-T6 aluminum using Rotor's Trinity Drilling system for 15% less weight than the original. Four strain gauges in the axle and two additional sets in the right crank arm provide even measurement of power from both legs, which is transmitted using 2. 3 Ghz Bluetooth or ANT+ to any smart cycling computer. The rechargeable Li-ion battery boasts a whopping 250 hours of worry-free riding. The 2INpower SL Crankset blends lightweight performance with essential power data for the most passionate road riders.
