Wolf Tooth
Wolf Tooth Components is an American component manufacturer founded in 2013 and based in Minneapolis, Minnesota, where its parts are machined. The company started with narrow-wide chainrings for 1x drivetrains and later expanded into headsets, dropper-post levers, seatposts, tools and small drivetrain adapters. Among its best-known products are the RoadLink and GoatLink derailleur extenders, which allow Shimano road and mountain rear derailleurs to be used with larger sprockets, and the Tanpan, which converts cable pull between Shimano road and mountain systems.
