Switch from the Vector S wattmeter pedal system with one sensor to a Vector 2S system with one sensor. The system is suitable for both standard pedal cranks (12 to 15 mm) and large pedal cranks (15 to 18 mm). As an enthusiastic cyclist, you can go one step further in measuring and monitoring your power output and your pedalling style.
Quickly bought, assembled and installed
The expansion of the Vector is very simple. You can assemble it in just a few minutes. No mechanic is necessary, and you don't have to wait long for the bike to come out of the workshop. You don't have to disassemble or reassemble any other components, and you don't have to mount additional sensors.
The secret of watt measurement
The Vector measures the torsion in the pedal axle when pedalling. The measured twist is compared with a factory calibration. This allows the Vector to determine how much force is applied to the pedal. Measurements are made several hundred times per second. Integrated accelerometers also measure cadence. The force sensors and all other electronic components are permanently and safely installed in the pedal axle.
