I use a kriega tool roll under the seat for touring. It contains proper versions of the standard tool kit plus my bung kit,cut down box key for removing my r&g crash bungs,a few nuts n bolts,zip ties,duct tape wrapped around wheel key ext,rubber gloves,hand wipes,snips,couple of scotch locs,superglue and my faithful gerber multi tool. All are the lightest options I have and have always managed despite breakdowns and small crashes. One tip I would mention tho. Share around the tools when group travelling, no point in taking twelve 10mm spanners,12mm spanners and sets of Allen keys.As always weight is no1 priority when packing for touring.
