I looked at the Lezyne site – they have one with the plug thing (how’s that for technical talk?) built in. Two birds in one stone.
I would really like the Silca one. Worry about the button and leaving a cartridge inserted after use (sometimes I have to use more than 1, but that was 12g threadless).
Time to think on this more. I have burped tires and just needed air … and I have had punctures. Sigh. If the Lezyne could do both the bacon AND a valvestem, that would be awesome.
Oh, if money and space in the saddle bag were not limitations…
