The invention relates to a chain guide roller (16) for a bicycle driveline having a chain (6), a multi-layer pinion arrangement (5) and a bicycle rear gearshift. The chain guide roller (16) comprises a bearing region rotatable about an axis of rotation, a tooth region constructed with teeth for meshing with the chain (6), and a support structure connecting the bearing region and the tooth region together. Guide regions are formed on the inner and outer sides of at least one tooth of the chain guide roller (16) in order to transversely guide the chain (6) substantially parallel to the axis of rotation. According to the invention, at least one inner guide region of the at least one tooth has a thickness dimension that is reduced at least in some regions relative to a center plane (PM) of the chain guide roller (16) in relation to at least one outer guide region, the chain guide roller (16) is arranged such that a chain section (6t) substantially tangentially away from the chain guide roller (16) can adopt a larger oblique angle ([lambda] i) in the outer direction (So) than in the inner direction (Si).
本发明涉及一种用于自行车传动系的链条导引辊(16),所述自行车传动系具有链条(6)、多层小齿轮配置(5)和自行车后换挡机构。所述链条导引辊(16)包括可以绕旋转轴旋转的轴承区域、构建有用于与所述链条(6)啮合的齿的齿区域,以及将所述轴承区域与所述齿区域连接在一起的承载结构。在所述链条导引辊(16)的至少一个齿的内侧和外侧的侧面上分别构建有导引区域,以便大体平行于所述旋转轴地横向导引所述链条(6)。所述至少一个齿的至少一个内侧导引区域相对于至少一个外侧导引区域具有相对所述链条导引辊(16)的中心面(PM)而言至少局部地有所减小的厚度尺寸,使得大体切向地从所述链条导引辊(16)离开的链条区段(6t)可以在外侧方向(So)上采用比在内侧方向(Si)上更大的斜角(λi)。
