Specialized S-Works Power Cranks - Dual Sided


Free UK Delivery on orders over £100

Specialized's S-Works carbon cranks have always been a superb superlight choice, so much so we often fit them to custom builds regardless of the frame's brand.

So naturally they make for an exceptionally light power meter crankset too - at launch these are the lightest and most accurate power cranks you can buy: 1.5% accuracy or better at every power level, cadence, gear, pedal offset, and riding position.

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)

Compatibility: Compatible with Shimano and SRAM gruppos.

Chainrings: Chainrings are sold separately, contact us for details.
