Wolf Tooth Tanpan Type:Derailleur Optimization reducing post-grind base prep andThe Negotiator. The Tanpan makes Shimano 10 and 11 speed road shifters work with 10 and 11 speed mountain bike rear derailleurs. Crossing boundaries and breaking down walls: the Tanpan brings the range and security of Shimano mountain rear derailleurs to Shimano equipped drop bar bicycles. This means a greater gearing range for bigger adventures, better chain security for rough terrain, and lighter weight and reduced complexity for the daily commute.
