I am also using a kayak bung in my steerer with the Leyzne pocket drive pump, credit to packer. Pump is very low volume but I never really use it anway.
I’m using the Zefal Z Bar Tyre Plugs in one grip (anchovies, tyre plug tool, chain links) and I’ve got a tyre lever in my second grip with standard bar end plug.
I lost the other side of the Zefal Z Bar kit due to it rattling loose, however you don’t need that piece. Sahmurai SWORD is an alternative to the Zefal kit.
I’ve then got my Topeak Ninja T Mountain multitool which includes a second tyre lever and chain tool attached to my bottlecage.
I am using these plugs (medium) but the fit is very tight, they could use a tiny bit of sanding to get them in a little easier.
