ROTOR 2INpower MTB Crankset Power Meter

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.

This power meter fits 30 MM MTB bottom brackets and is compatible with ROTOR Direct Mount Chainrings. See Compatibility tab for more information.

Power Measurement:

This ROTOR power meter has two power sensors (bottom bracket and right crank arm) and measures power from both legs. It is also able to measure your left vs. right leg power.

Dual-leg power measurement, can measure left vs. right leg power, accurate to within +/- 1.0%, 250 hours of battery life, rechargeable battery, ANT+ and Bluetooth compatible, 2-year warranty. See Specs tab for more information.

Advice From Our Staff:

This 2INpower is pricey and we understand it’s not in everyone’s budget. However, here’s why we like it: it measures power from both legs, provides left vs. right leg power and the aluminum crank arms are light and stiff. In addition, this power meter makes it easy to run oval rings if that’s your thing.

 

Options For This Power Meter

The ROTOR 2INpower MTB Power Meter is available in the following configurations:

  • Crank arm lengths: 165 mm | 170 mm | 175 mm
  • Chainring sizes: 30 | 32 | 34 | No Chainrings (if you already own them)
  • Chainring shapes: Round | Q-Ring (Oval) | No Chainrings (if you already own them)

Please note – the ROTOR 2INpower MTB is only compatible with ROTOR Direct Mount MTB Chainrings.

 

Other Versions to Consider

INpower Version: While the 2INpower you are viewing on this page measures power from both legs, we also have the more affordable ROTOR INpower DM MTB Power Meter which is a complete crankset but measures left leg power only.

ROTOR MTB Power Meter Compatibility

Chainrings: The ROTOR 2INpower MTB is compatible with ROTOR Direct Mount MTB chainrings, which can be purchased on this page along with the power meter.

Bottom Bracket: This power meter fits 30 MM bottom brackets. If you currently have a 30 MM crankset on your bike, you should be able to re-use your existing bottom bracket. However, if you are chaining spindle sizes, you will need to replace your bottom bracket.

2 reviews for ROTOR 2INpower MTB Crankset Power Meter
  1. Agustin Vega-Crespo (verified owner)

    Solid PM! Love the oval q ring and solid power reading in bumpy fire roads and single trails
    You have to get it with a bottom bracket and installation is relatively easy if you have the tools.
    Still figuring out the power readings as average power shows higher than NP – likely computer head setting
    Will do in the next weeks a test on a smart trainer, this power meter and power two pedals to assess discrepancies.

    Costumer service was outstanding! Will most certainly buy from this site! Great job guys ????

      Hi Agustin. Thank you for this awesome review on your ROTOR 2INpower MTB Crankset. We are happy you liked them – a great power meter indeed. We hope you continue to enjoy them! We appreciate your business and please let us know if there is anything else we can do! Ride safe!

    I bought this power meter to train for the Leadville MTB Trail 100. I paired it with a SRAM Eagle 1×12 and just absolutely love it. The information that you can get from the Rotor App and the dual sided power meter is pretty incredible when you take the time to analyze it and figure out how to use it to improve your performance. Well worth the price.

    • Power Meter City

      Hi Andrew. Glad you like you ROTOR 2INpower MTB. It’s quickly becoming our best-selling MTB crankset. Good luck on the Leadville 100 and let us know if there is anything else we can do.
