带磨损指示器的由复合材料制成的自行车车轮用轮圈和包括这种轮圈的车轮
摘要：
这种由复合材料制成的用于自行车车轮(60)的轮圈(1)包括两个相对侧面(5)，在该两个相对侧面上形成有两个相应的制动滚道(20)，所述两个制动滚道由于制动而遭受磨损，并且其特征在于，该轮圈在所述制动滚道(20)中的至少一个制动滚道处包括至少一个第一外层(25)和磨损指示器(40)，该磨损指示器适于指示何时轮圈(1)已经在制动滚道(20)处达到预定磨损水平，该磨损指示器在轮圈(1)中布置在相对于第一层(25)的内侧位置中。通过这种方式，磨损指示器(40)不对轮圈(1)的外表面造成最轻微的损伤并且因此不对轮圈的机械强度造成最轻微的损伤。
摘要（英）：

This rim (1) for a bicycle wheel (60) made from composite material comprises two opposite sides (5) on which two respective braking races (20) are formed that are subject to wear as a consequence of braking, and is characterised in that it comprises at at least one of said braking races (20), at least one first outer layer (25), and a wear indicator (40), suitable for indicating when a predetermined level of wear has been reached by the rim (1) at the braking races (20), arranged in the rim (1) in an inner position with respect to the first layer (25). In this way, the wear indicator (40) does not in the slightest blemish the outer surface of the rim (1) and therefore its mechanical strength.
