A quick release lock with “memory” system for cymbals, which allow drummers and percussionists to have an accessory that lasts longer and is more comfortable. Instead of using a classic felt, which may results in a crack on your cymbals, Techra developed its own techno polymer. Patented MEMORY system allows your pressure adjustments to be retained and highly elastic “synthetic felts” improve the sound of your music. All of these components mixed in a rapid, easy & steady, one-hand operation!
