New Rotor INspider Road Power Meter – Lighter, Smarter, More Aero

This new version of the Rotor INspider Road Power Meter is now better in every way – lighter, more precise, more aerodynamic, and about 10% cheaper.

• Lightweight & Aero: Weighing just 128g and only 12mm thick, it’s up to 28g lighter and more aerodynamic than before.
• Enhanced Compatibility: Fits more bikes with support for PressFit, BSA threaded, and T47 bottom brackets. Compatible with 24mm or 30mm axles, and adaptable to carbon or alloy cranks with round or oval 1x or 2x chainrings.
• Precision & Intelligence: Now with +/-1.5% accuracy, recording power 120 times per second for more detailed data output. Faster pairing and 75% longer runtime keep you riding longer.

Entirely made in Spain, the Rotor INspider Road is the ultimate power meter for road, gravel, and triathlon riders looking to elevate their performance.
