Dynaplug BICYCLEチューブレスタイヤ修理プラグ。

After going tubeless on my road bike (Schwalbe Pro One) I tried other, similar, products with just the 'bacon strips.' Those worked well enough but worked their way out after 50-100 miles. After swallowing the $60 price-point for the Dyanplug pill, i started using these. I had a run of bad luck with punctures but the "soft nose tips" got me back on the road very quickly. I had one instance where i hit a big hole seemingly right on where an existing plug was in my tire and it must have opened more because it started to spray sealant. I pulled over, plunged another plug in and while that sealed the deal, it dislodged the tip of the first which rattled in the tire for the rest of the ride - but i was sealed from leaks and that's what counts. The tire was pretty worn so i ended up taking it off and replacing, but the other two plugs looked good (see pic) I've re-upped with the new "bullet tip" normal-sized plugs as I am mildly concerned with the pointy ones damaging the rim tape should the tire go flat with one stuck in there. They are a little more difficult to plunge in but are shallower than the pointy tips and I feel a bit safer for my rim tape. At $2/plug it's a great deal compared to replacement tubes or a new tire and in my experience, they are permanent fixes as the tip keeps them from popping out and the sealant adheres to the plug. The longest i've ridden a dynaplug is 1,000 miles. The tire will wear out before the plug comes out.

Love these. Best tire plugs on the market for mountain bikers. And the plug kit is neat and so compact. A must have for a mtb tool kit .

dynaplugs work great in general, but the bullet tips are straight up useless.
