Patent attributes
A bicycle sprocket comprises a sprocket body and a plurality of chain-driving teeth. The plurality of chain-driving teeth comprises a first tooth and a second tooth. The first tooth has a first radial length radially defined from a reference line to a first radially outermost end. The second tooth has a second radial length radially defined from the reference line to a second radially outermost end. The second radial length is in a range of 1.5 mm to 2.9 mm. A shortest distance is defined between the downstream circumferential surface and a first intersection point of the circumferential center plane and an additional reference line. The shortest distance is equal to or larger than 2.0 mm. The additional reference line is defined at a reference position radially outward spaced apart from the reference line by 1.5 mm.
