It is a tool that puts a gear between three plates, hooks it on a protruding gear, and attaches and detaches a small steel gear from 12T to 18T. The left and right wrenches can be used properly according to the number of gears, and small gears can be replaced quickly. Since there is no need to wind the chain, you can expect to shorten the work time of mechanic staff and athletes who change gears many times a day. In addition, COG1218 is also effective for small gears that are engaged and cannot be disengaged because there is no need to worry about chain elongation or breakage. The surface treatment is RoHS compliant, environmentally friendly black trivalent chrome plating. It is a surface treatment that is easy to get fingerprints, but we appreciate your understanding.
* Cannot be used for small gears made of aluminum or carbon. It may cause damage.
