"Perhaps no other cycling tool is quite as iconic as the 13mm - 28mm Shop Cone Wrench from Park Tool. Often replicated, never duplicated, these Cone Wrenches are shop-grade quality and promise years of trouble-free performance. Park designs the ""Y"" head with more material where it's needed for strength and durability and its precise sizing and a military grade industrial phosphate finish ensure a snug fit and corrosion resistance. It's built thin for use on the narrowest of adjusting cones and its vinyl-dipped handle in signature Park blue for comfortable use."
