A method for capturing and evaluating sensor data while riding a bicycle on a path and a bicycle component, including at least one barometric pressure sensor for capturing an air pressure signal for the ambient pressure on the bicycle during the ride, at least one stagnation pressure sensor for determining at least one stagnation pressure value on the bicycle during the ride, and a computer which is configured and set up to derive on the bicycle during the ride from the air pressure signal, a corrected ambient pressure value for the ambient pressure, taking into account the obtained stagnation pressure value.
