A fixed-stroke cam connects to a precision paddle, while a rotating slider adjusts stroke length by moving closer to or farther from the paddle’s center. This design reduces friction and wear, keeping performance consistent session after session. A first-of-its-kind system built to keep your flow uninterrupted and your performance unmatched.
