Park precision spoke nipple wrench. This is the genuine professional version of the spoke wrench that everyone else copies.
Color coded to distinguish size at a glance. Rubber coated and ergonomically shaped for comfort. Precision sizing, hardened and nickel plated. Made in the USA.
This is the SW-0 model, which is for nipples sized 0.127" (3.23mm) which is typically DT, Wheelsmith and others. As always, measure first - or buy one of each size so you always have the right size on hand.
