I have a large saddle bag , the pump goes across the inside of the bag ..
the bag stays on the bike, no one bothers it . so the tube and such are in a side pocket..

[Add] .. reusable zip ties and velcro straps tie the pump inside my Carradice Bag



a full length frame-fit pump will move more air than a short Minipump ..

(i have frame pumps on my road and touring bikes)

but it sits out on the frame .. IDK where you park .. @ work.

if people steal anything not bolted down, there.
