The Knickerdropper
The Knickerdropper
The Knickerdropper is based on the legendary Wormburner frame, but with enhanced features to improve user-friendliness. With an extra 3” of ground clearance and a rear end that’s 2 inches shorter, this frame offers a more aggressive stance while reducing chain slap.
