Topeak DuoSpoke Wrench (M7/M9)

Topeak's DuoSpoke Wrench is the perfect tool for lacing up new wheels or truing your old ones. It comes with two different Mavic-specific spoke sizes on either side of the wrench, so you've always got the right one at hand. It also includes a 3-size spoke holder to prevent the spoke from turning with the nipple.
