KÉO POWER
David Montcoutié
Tour de France 2012
LOOK developed the first pedals capable of measuring pedaling cadence, a distinct
measurement taken at the left and right hand spindles.
Using technology by Polar (inventors of the heart rate monitor) the information is visible
directly on the display. Kéo Power is an accurate and reliable product aimed at cyclists
keen on improving their pedaling technique.
ACCURATE
MEASUREMENT
The Keo Power permits very accurate
measurement of the power and cadence.
Each axle is equipped with 8 strain gauges
permitting very accurate measurement
of the axle deflection and so of the forces
applied to it.
The deviations in accuracy are less than
2%. The axle electronics are designed to
measure forces up to 170kg, obviously the
axle can support much larger forces. The
cadence is measured using a reed relay
placed in the axle of the pedal.
Through the force and cadence
measurement, the Keo Power is capable
of giving the power. The information is then
sent to the POLAR transmitter, which sends
it wirelessly to the computer via the WINd®
protocol.
WIRELESS
Each pedal senses the cyclist’s power and
rate through the pedal spindle and transfers
them to transmitters (fixed on the crank arm)
which send them directly to the computer
using wireless technology.
8 stress gauges per spindle permit force measurement
with very high accuracy (
