Installation

The KeO Power has an auto-calibration function, performed automatically on startup. It accounts for temperature and other factors that can skew strain gauge readings.

Installation is relatively easy — certainly quicker than a crank-based system. The only difficultly lies in the fact that the axle must be aligned correctly with the crank for the system to calculate power correctly. Look’s solution is to mark the axle with a small indent, which must be aligned at 90˚ to the crank. A locknut in between the pedal body and the crank is then tightened down onto the crank to create a firm hold.

The pedal threads into a crank as usual, until the end of the axle is flush with the back of the crank and the mark sits at 90˚, then the locknut is tightened down onto the front of the crank using a regular 15mm pedal wrench. Look provides a special 8mm wrench to make the process easier — simply align the wrench with the crank arm and then tighten the lock nut. The method is considerably easier to perform than to explain, I assure you.

The cadence sensor is internal, so there are no extra magnets to mount anywhere. Crank length selection is performed on the transmitter itself.

As a contact point, wear is a concern with a pedal-based power meter. Thankfully, pedal bodies will be available separately from Look, so there will be no need to spend the full $2200 again in a few years when the contact surface wears out.
