I have no idea where these things have been my whole life. Finally had an opportunity to try my dynaplug racer, unfortunately, it was on my own rear tire. Came up short, had a pinch flat at the bead. This was easily fixed with my dynaplug racer and C02 in about 5 minutes. Would have been a lot quicker but this was my first time. Intuitive and easy to use and of course great prices and free shipping from BTD!
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.
