A bicycle sprocket comprises a plurality of sprocket teeth including at least one first tooth and at least one second tooth. The at least one first tooth has a first non-driving surface including a first non-driving surface portion and a second non-driving surface portion so that a first ridge is formed between the first non-driving surface portion and the second non-driving surface portion. The at least one second tooth is configured to initially engage with the bicycle chain in a shifting operation. The at least one second tooth is disposed adjacent to the at least one first tooth. The at least one second tooth has a second non-driving surface including a third non-driving surface portion and a fourth non-driving surface portion so that a second ridge is formed between the third non-driving surface portion and the fourth non-driving surface portion.
