ROTOR INspider ALDHU Road Power Meter Crankset

The ROTOR INspider ALDHU Road Power Meter Crankset is the first of its kind – a spider-based power meter that can be used on virtually any bike! It is compatible with any of ROTOR’s newer direct mount cranksets and you can use it on your road, CX, gravel or track bike.

In addition, ROTOR cranks come in all shapes and sizes. You can select 24 and 30 mm spindles and crank arms from 150 to 175 mm. This allows to you run the crankset that fits both your bike and your style. You can even set up the INspider in a 1x or 2x chainring configuration using any ROTOR 110 BCD 4-bolt chainring.

The ROTOR INspider records data via four sets of opposing gauges. This results in a high degree of accuracy (+/- 1.0%). It also means the power meter can measure left and right leg power balance. The INspider features ANT+ and Bluetooth SMART and has a USB-rechargeable battery with 200-hour battery life.

 

Key Product Details

Compatibility:

This power meter fits 24 MM and 30 MM road bottom brackets and 110 BCD 4-bolt chainrings. See Compatibility tab for more information.

Power Measurement:

The ROTOR INspider power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Dual-leg power measurement, accurate to +/- 1.0%, 200 hours of battery life, 1x and 2x compatible, works great with oval chainrings, rechargeable battery, left/right power balance, ANT+ and Bluetooth compatibility. See Specs tab for more information.

Advice From Our Staff:

These are fantastic cranksets. The ROTOR power meter measures power from both legs, is accurate and reliable. The ALDHU crank arms, while not carbon, are some of the nicest aluminum arms we sell. In addition, you can also run this power meter in a range of configurations (different crank arms, spindle sizes and chainrings) to fit your needs.

 

Options For This Power Meter

  • Crank Arm Length: 150 mm | 155 mm | 160 mm | 165 mm | 170 mm | 172.5 mm | 175 mm
  • Chainring Size: 50/34 | 52/36 | 53/39 | 54/39
  • Chainring Shape: Round | Oval

Other Versions to Consider

Carbon Version: We also have the ROTOR INspider ALDHU Carbon Road Power Meter Crankset which features ROTOR carbon crank arms. This version is more expensive, but it is lighter and stiffer. Please note, the carbon version ONLY comes in a 30 mm spindle size.

More Affordable VEGAST Crank Arm Version: We also sell the ROTOR INspider VEGAST Road Power Meter Crankset which comes with more budget friendly crank arms. The VEGAST crank arms are not quite as nice and they are a bit heavier.

Compatibility

Chainrings: This power meter is compatible with ROTOR 110 BCD 4-bolt asymmetric chainrings which can be purchased on this page along with the power meter and cranks.

Bottom Bracket: This power meter uses a 30 mm spindle and must be used with a 30 mm bottom bracket.

Note 1 - If you would like this power meter crankset with a ROTOR ALDHU 24 mm spindle, we are happy to arrange that (price is the same). However, please note the 24 mm version is not offered in 150, 160 or 167.5 mm crank arm lengths.

Note 2 - This power meter can also be ordered with SRAM AXS chainrings. Please contact us for availability.

Note 3 - The INspider does not fit Trek bikes that have a T47 bottom bracket.
