Highlights
Why we rate it
Hidden inside the spindle
The electronics live in the DUB spindle, so the crank looks the same as a standard Force AXS set.
Left-side measurement
Measures power from the left leg and doubles it to give total watts, using Quarq technology.
Long battery life
A user-replaceable AAA lithium battery runs for over 400 hours.
Minimal weight penalty
Adds under 40g over a standard Force AXS crankset.
