A six inch adjustable crescent won't fit anything on my bike, and it's almost 40 yo.
As for the OP.... I can only agree with those that ask, why are not all those things they mentioned already set before the ride?
There are many compact tool kits for bicycles, if the OP feels that one is needed to carry, then pick the one that has the tools in the sizes that fits the bike they ride.
