ROTOR INspider KAPIC Carbon MTB Power Meter
The ROTOR INspider KAPIC Carbon MTB Power Meter is the first of its kind – a spider-based power meter that can be used on virtually any bike! Compatible with any of ROTOR’s newer direct mount MTB cranksets, the INspider records data via four sets of opposing gauges. This results in a high degree of accuracy (+/- 1.0%) and also means the power meter can measure left and right leg power balance. The INspider also features ANT+ and Bluetooth SMART and has a USB-rechargeable battery with 200-hour battery life.
Key Product Details
Compatibility:
This power meter fits 30 MM MTB 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, lightweight carbon cranks, fits boost and super boost frames, 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:
This is one of our favorite MTB cranksets. Here’s why: the ROTOR power meter measures power from both legs, is accurate and reliable. The KAPIC carbon crank arms are super lightweight and stiff. One consideration however is the smallest ring you can run on it is a 34T vs. the commonly used 32T.
Options For This Power Meter
- Crank Arm Length: 165 mm | 170 mm | 175 mm
- Chainring Size: 34T | 36T | 38T
- Chainring Shape: Round | Oval
- Spacing: Boost | Super Boost
Compatibility
Chainrings: The power meter is compatible with ROTOR 110×4 Chainrings, which are available in round and oval and 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.
Frame Spacing: The power meter fits both Boost and Super Boost Frames based on the version ordered.
