Double-Ended Spoke Wrench — Mavic 7-Groove

Our dual-ended spoke wrenches are a convenient and functional option for truing bicycle wheels with specialty spoke nipples. The shape of the SW-12 is ideal for truing wheels while using a spoke holder to prevent aerodynamic spokes from rotating. Each SW-12 is made in the USA and is precision machined, nickel-plated, and vinyl-coated for long life.
