摘要 本發明涉及用於自行車齒盤的齒冠的銷(110),該銷(110)包括: 沿該銷(110)的縱向軸線(X)延伸且構造成固定至該齒冠的安裝部(20),該安裝部(20)具有沿與該縱向軸線(X)垂直的橫向方向(Y)的第一尺寸(21a); 與該安裝部(20)關聯且沿該橫向方向(Y)具有比該第一尺寸(21a)大的第二尺寸(21b)的鏈條接合部(30)。 該鏈條接合部(30)包括面向該安裝部(20)且構造成接合自行車鏈條的鏈節的板的第一面(32)和相對於該安裝部(20)以相反方式面向的第二面(34)。 該第二面(34)包括相對於該縱向軸線(X)傾斜比90˚小的第一角度的至少一個第一表面部(136),在該銷(110)的縱向截面平面中量測該第一角度,該縱向截面平面包含該縱向軸線(X)且垂直於該橫向方向(Y)。 The invention relates to a pin (110) for a crown of a bicycle crankset, the pin (110) comprising: - a mounting portion (20) extending along a longitudinal axis (X) of the pin (110) and configured to be fixed to said crown, said mounting portion (20) having a first dimension (21a) along a transversal direction (Y) perpendicular to said longitudinal axis (X); - a chain engaging portion (30) associated with said mounting portion (20) and having a second dimension (21b) greater than said first dimension (21a) along said transversal direction (Y). Said chain engaging portion (30) comprises a first face (32) facing towards said mounting portion (20) and configured to engage a plate of a link of a bicycle chain, and a second face (34) facing on the opposite way with respect to said mounting portion (20). Said second face (34) comprises at least one first surface portion (136) inclined with respect to said longitudinal axis (X) by a first angle smaller than 90°, said first angle being measured in a longitudinal section plane of the pin (110) that contains said longitudinal axis (X) and is perpendicular to said transversal direction (Y).
