The data provided is consistently reliable, mirroring the output from other trusted power meters I’ve used in the past, especially when comparing left-leg power readings.

What makes these pedals particularly effective for their intended use is their ability to translate the forces applied on the left pedal into total power output. While it’s a single-sensing system (measuring left leg only and doubling it for total power), the accuracy holds up remarkably well for a wide range of riding styles. I found the power readings to be responsive, tracking changes in effort accurately during sprints, climbs, and steady-state efforts.

A key strength is their robustness on uneven terrain. Unlike some power meters that might be sensitive to sharp impacts or vibrations, the Rally XC100’s sensors housed within the spindle seem well-protected. This resilience is crucial for gravel and cyclocross where pedal strikes are almost inevitable.

The main weakness, inherent to any single-sensing power meter, is the assumption that both legs produce equal power.
