Our double-ended spoke wrenches are a comfortable and functional option for truing bicycle wheels with specialty spoke nipples. The shape of the SW-13 is ideal for truing wheels while using a spoke holder to prevent rotation of bladed aero spokes. Each SW-13 is made in the USA, and is precision-machined, nickel plated and vinyl-dipped for long service.
