PARK TOOL TOOLS
Today's aero-arms race forces manufacturers go to extreme measures to cheat wind resistance -- including hiding the spoke nipples inside the rims. The innovative Park Tool SW-15 3-Way Internal Spoke Nipple Wrench has three different sized wrenches to fit nipples hidden inside of rims.
The SW-15 features a 3.2mm square drive, and 5 and 5.5mm hex drive sockets. The low-profile walls fits perfectly in the tight surroundings of most rims, and the Park Tool Blue vinyl coating offers a secure grip. This wrench works with wheels made by FSA, Blackwell, Planet-X, HED, Rolf, Bontrager, Campagnolo, and Mavic. Like all Park Tools, the SW-15 3-way Internal Spoke Nipple Wrench has a lifetime warranty.
