100g lighter than any other power meter (measuring total bike weight), these are also top performers with +/-1.5% real world accuracy - tested and validated.
These are dual sided power cranks, so you can measure the output from both legs independently.
They're also supremely easy to use - the "set it and forget it" temperature compensation firmware means that they remain accurate in all conditions without any fiddling around. Setup and diagnostics are made easy by Specialized's Power app, available for both iOS and Android.
The hollow carbon crankarms, carbon spider and oversized alloy spindle are supremely stiff and lightweight (just 440g in 172.5mm length).
The S-Works Power Cranks work with ANT+ and Bluetooth devices, for maximum compatibility.
Fit: Specialized road frames with OSBB or PF30 bottom bracket shell (and most BB30 road frames regardless of brand)
Spider: Compact 110 BCD Carbon Spider (also compatible with 130 BCD spider, sold separately)
