Using the Xeros Bass Wheel Brake is a breeze: Tilt your bass to its normal upright position and it immediately stops rolling. In fact, playing your bass with the Xeros left attached to the bass is now possible with the Xeros Bass Wheel Brake. Perfect for those outdoor gigs in the soft grass. Fine quality steel, heavy duty, as you have come to expect from Xeros. Install the Xeros Brake on any Xeros Bass Wheel, as well as Meisel, Gaines, and Onyx bass wheels. Kit includes brake, shaft bolt, and locknut, for easy retrofit. Wheel sold separately (item 1720W) or as a wheel and brake kit (item 1720WB).
