These double-ended spoke wrenches are a comfortable and functional option for truing bicycle wheels with specialty spoke nipples. The shape of the SW-9 is ideal for truing wheels with limited access to spoke nipples, such as on small wheels with a high spoke count, or while using a spoke holder to prevent rotation of bladed aero spokes. Each SW-9 is made in the USA, and is precision machined, nickel plated and vinyl dipped for long service.
