Not suspension related but...
In my first tour, i kept a cheap mini 12v compressor under the seat with tire plugs. Only needed to use it once.
On my second tour, i got a li-ion portable compressor thats also palm sized. Much more convenient for quick pressure checks ala cold mornings or elevation changes.
The li-ion almost had a shot at refilling a 200/x0-r18 tire on a broke down travellers bike. Unfortunately, i had mis sed plugging a hole. Having already patched up two of em. Probably woulda done the job.
