The Multi 19 Crank Brothers is a very stable tool with which you can do your most important driving screws at the wheel with quick releases on the wheels. The individual tools are very solid and do not fray as quickly as with cheap tools. At the edge you can set the smooth running of the tools on the personal preferences via Allen. Chain and spoke tool also work very well, particularly the spoke clamp fits comfortably in your hand. A lightweight, it is not, so people should perhaps should select another tool attention to the last gram numbers. The shell is just a gimmick, but it still looks chic and ensures that in the bag from sticking to the tool.
