@redjives it is probably only with different bike, I just don't need the 15mm wrench because it is useless for modern bikes also the pliers are only useful for cable adjustments for me so I didn't bothered to pack them.
It really depends what bolts and nuts you have on your bike. And as you pointed out for 2 people it can be divided so you can bring more tools. I traveled with the mindset to only patch the bike so I could get to the nearest bikeshop not to do complete repair.
