Various works such as brake pads, cables, a pinion or chain change I get out now, as well as the setting braking or circuit. Can mend a tire yourself, my son already. The tool of this box helps in all areas. The box is suitable for the occasional screwdriver, it is not a professional tool. That would be even more expensive. But with me it reaches the tool included in the box and its quality, the good complements my previous tool. In general I find these toolboxes very convenient because you have so everything safely stowed in one place.
That's a decent Werkzeukasten for hobbyists at a reasonable price. It contains all the basic tools that you need to keep the bikes in the family income. The quality of the tools is sufficient for this purpose, but not for more. I think 4 stars are a proper assessment.
