Specialized Power Cranks Ultegra Upgrade Kit

If you're looking for the most cost effective way to get superbly accurate power measurement, this is it.

+/-1.5% accuracy, tested on Specialized's "win mill" and validated by the Locomotion Lab in Boulder, Colorado.

This power crank simply replaces your left (non-drive-side) Ultegra crank. It'll work happily with ANT+ and Bluetooth devices, and Specialized's Power app, available for iOS and Android, makes setup and diagnostics a doddle.

A single-sided solution like this won't provide quite the depth of information that a dual-sided solution offers, but then again it's an extremely quick, easy and economical way to get into power measurement.

  • Shimano Ultegra 8000 generation crank arm
  • Note: Right crank arm and spider are NOT included!
