A bicycle rim, apparatus for printing a bicycle rim and printing method for printing a contactless imprint on an annular rim body

摘要

A bicycle rim has a tire mounting portion 12, an inner circumferential portion 14, a first side portion 16, a second side portion 18, and a first contactless imprint 32. The inner peripheral portion 14 is provided radially inwardly of the tire mounting portion 12 with respect to the rotational center axis A1 of the bicycle rim. The first side portion 16 includes a first curved surface 16A. The first contactless imprint 32 is at least partially provided on the first curved surface 16A. A first tangential line TL1 is defined on the first curved surface 16A in which the first non-contact imprint 32 is provided. A first area angle TA1 is defined by the first tangential line TL1 and a reference plane RP perpendicular to the rotation center axis A1. The first area angle TA1 is greater than 30 degrees.
