The Tubeless Tire Repair Kit fills holes which sealant can’t. Simply affix one of the included plugs to the Dynaplug® Racer tool, slip it inside the hole, and pull the tool back out. The viscous plug remains in place and fills the hole, repairing the tire.
I am carrying this with my road tubeless set-up. Still waiting for a chance to use it.
My friend has used it to fix a hole about 4 mm that wouldn't seal in his Mavic road tire . He is still running the tire tubeless with several 100 more miles on it after the puncture .
Very light and useful item.
