Abstract: A wheel component for sports and racing bicycles with an annular tire and a central tread surface, which in proper use in straight-ahead travel on a plane ground circumferentially makes contact with the surface of the ground, and which opens up a central longitudinal sectional plane. Planar aero elements are configured on the surface of the annular tire, laterally spaced apart from the longitudinal sectional plane. The aero elements are configured as depressions in the surface of the tire and are disposed on the side surfaces and define angular bands rotating on the side surfaces. The surface proportion of the aero elements to the surface of an angular band is larger than 5% and less than 25%.

Abstract: 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.

Abstract: A bicycle component with a measuring device with a housing and a measuring probe connected therewith, including a probe body having an exterior opening. The exterior opening is connected through an air guide with a barometric pressure sensor disposed remote from the exterior opening. The air guide includes at least two air ducts and an internal chamber that is connected with two air ducts. One of the air ducts is configured as a supply duct and begins at the exterior opening. The other of the air ducts serves as a sensor duct and connects the internal chamber with the barometric pressure sensor.

Abstract: A spoke for an at least partially muscle-powered bicycle and wheel including a spoke where the spoke comprises a spoke body with a hub-side, first end and a rim-side, second end and the first end and the second end are remote from one another. The spoke body is elongated and includes at least one first center region disposed closer to the first end than to the second end, and at least one second center region disposed closer to the second end than to the first end. The first center region and in the second center region of the spoke body each include flattened cross-sections substantially accommodated in a longitudinal plane. In the second center region the spoke body is configured more asymmetric than in the first center region.
