The Park Tool SW-13 is a precision-engineered double-ended spoke wrench designed for truing bicycle wheels fitted with speciality spoke nipples.
Its distinctive shape works perfectly with spoke holders, keeping bladed aero spokes stable during adjustment and preventing unwanted rotation. Crafted in the USA, each wrench is precision-machined and finished with nickel plating and a protective vinyl dip for durability and long-lasting performance. The comfortable design makes wheel truing straightforward and efficient, whether you're a home mechanic or professional technician. Ideal for maintaining wheels with Mavic 6-spline and similar speciality nipples.
