Just spent 2 hrs by the side of the road this evening. A bolt popped out of my front derailleur, 2 minutes to go back and retrieve, 2 minutes to find where it came from and set bike to fix, the rest of 2 hrs attempting to use my Topeak mini multi-tool to put bolt back. The placing and screwing in of the bolt was difficult, it meant putting pressure in 2 directions while using the driver, this is where the tool failed badly. 1st the tool had loosened all by itself in my saddlebag, the remedy would have been another multi-tool since the loosening occurred at its own bolts (!), I used the key from my cycle lock to partly remedy this since I needed maximum leverage, but it was a dismal failure since the tool has a design weakness that means it pulls away in the turn when levering under pressure, I took it apart just so I could grip the shaft of the driver properly. I have vowed never to be so stuck again and am looking for a tool or tools that will actually do the job required. Any suggestions?
