Incredibly ingenious. =-)
I have not ridden a bike in about 35 years, much less repair or take one apart (something I did quite often at when in school). Could you elaborate on dimensions of this 'presta' style stem (outer diametre) and most important, on that pressure gauge (brand, price, etc.) you are using?
I have certain doubts as to the possibility of my being able to use this type of arrangement as the Cimbali PFs that came with my Junior D/1 are not like yours and only have a 7.0 mm hole with no threads.
Thanks for posting your brilliant idea.
