ROTOR INspider VEGAST Road Power Meter Crankset

The ROTOR INspider VEGAST Road Power Meter Crankset features the INspider paired with ROTOR’s budget friendly VEGAST crank arms. The result is a dual-sided crankset that performs as good as it looks, without costing as much as the ALDHU version. In addition, the VEGAST comes in several crank arm lengths and fits both 24 mm and 30 mm bottom brackets.

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 VEGAST crank arms are modeled after the slightly more expensive ALDHU arms, but are a bit more affordable. 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

  • Crank Arm Length & Spindle Size: 165 mm | 170 mm | 172.5 mm | 175 mm (both 24 mm and 30 mm spindles)
  • Chainring Size: 50/34 | 52/36 | 53/39 | 54/39
  • Chainring Shape: Round | Oval

 

Other Versions to Consider

ALDHU Version: We also have the ROTOR INspider ALDHU Road Power Meter Crankset which features ROTOR ALDHU crank arms. This version is a bit more expensive, but the ALDHU arms are nicer (stronger and lighter).

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 either a 24 mm or 30 mm spindle and must be used with the correct bottom bracket.

Note 1 - This power meter can also be ordered with SRAM AXS chainrings. Please contact us for availability.

Note 2 - The INspider does not fit Trek bikes that have a T47 bottom bracket.
