In the latest issue of the International Journal of Sports Physiology and Performance, Look Keo Power pedals were tested for their validity and reliability.

The test, performed on 10 males familiar with laboratory performance tests, used Look's Keo Power pedals mounted to a stationary SRM ergometer, which is regarded as the most precise power meter on the market. Each of the 10 subjects performed two tests on the Ergometer with Keo Power pedals. The tests used a gradual increase in power, until exhaustion was reached, like a VO2 max step test, followed by 10 minutes of easy spinning. Then, the riders did three 10-second sprints, separated by three minutes of spinning at 100 watts.

The results were not flattering for the Look Keo Power system. "Power data from the Keo Power pedals should be treated with some caution," read the study.

Unfortunately, it is not often that cycling power meters are proven, or disproven, by scientific journals. To our knowledge, SRM, PowerTap, Ergomo, and Quarq are the only other power meters to be tested by journals. Both SRM, Quarq, and PowerTap power meters were given much better marks than the Keo Power pedals in separate tests.

Correction: An earlier version of this story stated that only SRM and Quarq have been tested by scientific journals. PowerTap and Ergomo were also tested.
