Wing bolts and washers: they can help to secure your cymbal and felt together tightly, making sure you’ll never miss a beat (or cymbal) because of cymbal rotation problems Smooth fitting sleeves: ensure that your cymbals are perfectly positioned at the optimum height in order to allow complete control of setting up your drum set and delivering good performance Quality felts: all pieces are made of quality fiber-optic felt which are designed to last longer and provide better protection for your cymbals
