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 (+/- 1.5%). 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
This power meter fits 24 MM and 30 MM road bottom brackets and works with a wide selection of ROTOR chainrings. See Compatibility tab for more information.
The ROTOR INspider power meter measures power at the spider and is therefore able to measure power from both legs.
Dual-leg power measurement, accurate to +/- 1.5%, 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.
- Crank Arm Length: 165 mm | 170 mm | 172.5 mm | 175 mm
- Spindle Size: 24 MM | 30 MM
ROTOR offers several different chainrings that fit this power meter…too many for us to list in the menus above! So on the Checkout Page, just tell us what chainrings to include in your order. No need to add the chainrings you want to your cart – the cost is included with the power meter here! Please view all available ROTOR power meter chainrings.
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).
Chainrings: This power meter is compatible with a wide selection of ROTOR 110 BCD 4-bolt chainrings. They are designed to work with 9-, 10-, 11-, 12-, and 13-speed groupsets.
Bottom Bracket: This power meter uses either a 24 mm or 30 mm spindle and must be used with the correct bottom bracket.
Note - The INspider does not fit Trek bikes that have a T47 bottom bracket.

Common Questions and Answers
Question: How do I determine what length my current cranks are so I can make sure I get the same size?
- Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
