ROTOR INspider MTB KAPIC Aluminum Power Meter
The ROTOR INspider MTB KAPIC Aluminum Power Meter features the new INspider MTB on a KAPIC crankset. The INspider MTB is a spider-based power meter that offers dual-leg power measurement. It’s accurate to 1.5%, has a 350-hour rechargeable battery and is extremely lightweight at only 105 grams. It fits both round and oval 1x chainrings which are available in sizes as small as 30T.
In addition, the KAPIC crankset is ROTOR’s go-to all terrain MTB crankset. It weighs just 545 grams (170 mm with 32T rings) and is also exceptionally stiff. It fits Standard (142 mm) and Boost (148 mm) frames.
Key Product Details
Compatibility:
This power meter fits 30 MM MTB bottom brackets and ROTOR 100 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 +/- 1.5%, 350 hours of battery life, fits standard and 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 new MTB cranksets. The INspider MTB measures power from both legs, is accurate and reliable. It’s also lightweight and works with round and oval chainrings as small at 30T. The KAPIC aluminum crank arms are not quite as light and stiff as the carbon version, but it’s still a very nice crankset and we think $899 for the power meter, cranks and chainring is a fair price!
