replacement Aluminum Cogs for TRS Plus 11-Speed Cassette, 33-46t, Black

A major selling point of e*thirteen Cassettes are their two-piece designs, which allow individual parts to be replaced as they wear. Depending on chainring size and style of riding, cassette wear will be different for all customers...but the good news is that you don't have to buy a whole new cassette when only one portion is worn out. Keep your cassette running smoothly with factory replacement parts.
