VELO-PERSO'S VERDICT
ROTOR 2INpower SL: our choice for true independent left/right power measurement
The ROTOR 2INpower SL combines a lightweight aluminium crankset with a true dual-sided power meter. Unlike systems that calculate or estimate left/right balance, it measures the power produced by each leg independently.
ROTOR's 2INpower platform has been a benchmark for years thanks to its accuracy, reliability and detailed pedalling data. At only 530 g in 170 mm without chainrings, the SL version retains these strengths while substantially reducing weight.
Our advice: choose the 2INpower SL when accurate independent left/right analysis matters. If minimum weight is your main priority and highly accurate total power is sufficient, an ALDHU Carbon + INspider remains the lighter alternative.

Lightweight despite dual measurement
CNC-machined 7075-T6 aluminium construction with a 30 mm spindle and a weight of only 530 g in 170 mm without chainrings.

2INpower SL or ALDHU Carbon INspider?
Choose the 2INpower SL when true independent left/right measurement and detailed analysis of power asymmetry are important to you.
Choose ALDHU Carbon + INspider when your priority is the lowest possible ROTOR power-meter crankset weight and highly accurate total power measurement is sufficient.
Which bottom bracket do I need for the 2INpower SL?
The ROTOR 2INpower SL uses a 30 mm spindle. The required bottom bracket therefore depends on your frame standard: BSA, BB86, BBRight, BB386EVO, PF30, T47 and others.

Is the ROTOR 2INpower SL available in 155 mm?
Yes. ROTOR officially offers the 2INpower SL in a 155 mm crank length. Velo-Perso currently has the 155 mm version in limited stock.
Does the 2INpower SL really measure both legs independently?
Yes. It independently measures the power generated by the left and right legs rather than simply estimating left/right balance.
What spindle diameter does it use?
The 2INpower SL uses a 30 mm spindle. Your bottom bracket must therefore match both your frame standard and a 30 mm crank spindle.
How long does the battery last?
The rechargeable Li-ion battery provides up to 250 hours of riding time.
Should I choose 2INpower SL or INspider?
Choose the 2INpower SL for true independent left/right measurement. INspider is particularly attractive when low weight, modularity and accurate total power measurement are the priorities.
