The only plug kit here with two plug diameters
PRO BIKE TOOL Tubeless plug kit, 10 plugs in two sizes
A tubeless plug kit with ten vulcanized butyl plugs in two diameters and a combined reamer and insertion tool in an aluminum canister.
What you are getting
A tubeless plug kit: ten plugs in two sizes — five 1.5 mm (0.06 in) and five 3.5 mm (0.14 in) — a combined reamer and insertion tool, inside a CNC-machined aluminum canister 2.8 cm (1.1 in) across and 7 cm (2.8 in) long that becomes the handle. 50 g (1.8 oz) stated, 57 g (2 oz) on the shipping record. $16.99.
It is the only plug kit here with two plug sizes
“5 × 1.5 mm (0.06 in) bacon strips for road bike tires and smaller punctures plus 5 × 3.5 mm (0.14 in) black strips for larger punctures.”
That matters more than it sounds. A plug has to fill the hole: too small and it leaks, too large and it will not go in without tearing the casing further. The KOM kit on this page carries eight 1.5 mm (0.06 in) strips only and suggests twisting several together; the Lezyne carries five of one unstated size.
Two diameters in one canister is the difference between fixing a road puncture and fixing a trail gash with the same tool.
The canister is the handle, and that is the design
“CNC-machined aluminum capsule protects the insertion tool and tire plugs while doubling as the tool handle during repairs.”
A plug has to be pushed through a tire casing hard. A bare insertion tool gives nothing to push on; a 7 cm (2.8 in) aluminum tube does. All three plug kits in this group do this, and it is the reason they are all aluminum rather than plastic.
Fifty grams, which is the heaviest of the three
KOM 25 g (0.9 oz), Lezyne 33.2 g (1.2 oz), this 50 g (1.8 oz). The extra weight is the extra five plugs and a fatter canister — 2.8 cm (1.1 in) across against Lezyne’s 2.55 cm (1 in).
The shelf intro asks “whether the case actually fits a saddle bag”. At 7 × 2.8 cm (2.8 × 1.1 in) this one does, comfortably. It is a bigger object than the Lezyne and holds twice as many plugs.
It says what a plug kit is for, which the shelf cares about
“Quickly repair punctures that are too large for tubeless sealant. Insert a rubber tire plug into the puncture, reinflate your tire and get back on your ride without removing the tire from the wheel.”
Two facts in one sentence: a plug kit is the step after sealant fails, and it works from outside. That is why tubeless riders need “a third thing entirely” in the words of this page’s introduction — a patch repairs a tube, and there is no tube.
Vulcanized butyl, named
“Vulcanized butyl rubber plugs.” A material rather than “bacon strips”, which is what the other two call them. Vulcanized butyl is what an inner tube is made of, cured so it stays elastic — the right thing to leave inside a tire that flexes.
What is not published
No plug length, no statement of how long a plug lasts in place, no reamer diameter, and no sealant compatibility. One real omission: nothing says whether a plugged tire should be considered a permanent repair or a get-home measure.
