The Muc-Off Two Prong Brush is designed for reaching hard-to-shift dirt on spokes, discs, shocks, cranks, linkages, and pedals. Its unique design features an impact-resistant, dual-density handle for maximum grip in wet conditions and durable nylon bristles. The twin brush heads can be altered and repositioned to reach even the tightest areas. To maintain brush performance, avoid use with boiling water and on hot parts; use warm water and allow hot parts to cool before use.
