With disruptors like Stages and upstarts like Watteam bringing power meter prices to more attainable levels, the bigger companies are reacting. Quarq dropped the chainrings to bring their crankset units in a little cheaper, and now Garmin’s simply cut the number of sensors in half.
The Vector S, which presumably stands for “single-sided”, drops the drive side power meter sensor and transmitter, leaving the left hand pedal to do all the work. The firmware is tweaked so the single pedal doubles the power output reading, then sends that number to your ANT+ compatible cycling computer. You lose the distinct left/right leg power measurements, but you save about $600.
It’s sold as a set, including the drive side pedal, Available for pre-order now for $899. That’s compared to the $1,499 for the dual sided system. An upgrade option will let you add the right hand power meter pedal in the future, too. Another pic and more details below…
The pedal can be ordered with standard or thick pedal pods depending on which cranks you’re putting it on. The standard pedal pods fit crank arms 12–15mm thick and 44mm wide. The large pedal pods fit crank arms 15-18mm thick and 44mm wide. You’ll also get the cleats and an ANT+ USB stick in the box.
