hey Imi, before I forget, a heads up re your pump strapped to the frame like that -- I wanted to mention how over the years, I keep my pump in a pannier, also during all my regular commuting, and a number of times the end cap, the part we unscrew to change the innards from presta to shraeder, has become loose from vibrations.
Once, the parts came off, but luckily was in my pannier and I found them in the bottom.

I've put this pump on a bike frame for day rides , but even then I'm quite wary of losing the bits if ever one didnt notice that it had become loose--essentially having a useless pump.

yes, it probably takes ages for this to happen, but I'm glad Ive been lucky those few times.
cheers
