I like the longest version of the Lezyne Road Drive, and carry it on the frame next to the bottle cage on the seat tube.
Many models from Lezyne have combination Presta/Schrader flex hoses, but the one supplied with the Road Drive is Presta-only. I could buy a different flex hose, but my own valves are all Presta, so I keep a
Schrader-to-Presta adapter from Cantitoe Road in my saddle bag in order to be able to offer a roadside assist.
