This tool also extensive repairs are traveling possible while it is still small and light. The quality of the tool is good and the price reasonable (in my view). Although it is not sufficient for any eventuality, but for almost any. If in doubt, you should try and see if you get changed with this tool a tire and each screw on the bike going and gets firmly halt.
Complete my tool is a small adjustable wrench to also eg 14mm nuts solve at the seatpost / tighten may or counter.
I can express not only a buy recommendation at this point, it's almost a must-buy.
