VittoriaUniversal Tubeless Tire Sealant - Tubeless Bike Tire Sealant - Ammonia Free Sealant for All Bikes

This sealant seals quickly and is easy to seat with. I use as little as 30ml per wheel on my road bike and seals so well, the rolling resistance is perfect and I can run super low pressures like 40psi. The sealant also isn't sticky and doesn't ball up like Muc-Off. I top it off every 4-6 months and works great.

The photos show two different holes in the process of sealing themselves.- I have Vittoria Corsa N.XT 30mm tubeless on my road bike. I generally ride long distances over city and country roads, so I swapped my earlier tubed setup for tubeless with the vittoria inserts about 6 months ago. Since then I have never had to call for a ride or repair a flat on the side of the road, something I really hated when it happened 50 mi from home... After about 4 to 6 months the fluid needs to be replaced. I picked up a piece of metal wire in my rear tire that would not seal any more. I decided to unmount the tire and remove the wire from the inside, and clean out the old fluid at the same time. With the N.XT and the inserts it is a pain to get the tire off the rim, but once you figure it out, it can be done. Use the tools from Vittoria: they are a big help in compressing the foam insert so that you can break the seal and get a lever under the tire bead. The N.XTs are a very tight fit on my wheels. Once I got the tire open, I wiped out the old fluid with a paper towel, pulled the wire out and pumped air back in with my pump. Then I added 30 ml of fluid through the valve stem, replace the valve and brought it up to pressure. The tire sealed itself right away and I am looking forward to another 6 months of trouble free riding.

I ordered this sealant because my tire had a slow leak and I had to add air every other day. Once I added this sealant, my tires have not gone low even a little bit. I definitely will be ordering this again for my next set of tires.

Sealed road bike tire on a tubeless wheel need an injector to make a messless job.

Works perfectly

This product would have probably gotten 5 stars if my Vittoria tubulars had removable presta valves but no. This is an important thing to know I would think. They advertise this sealant as able to work with all tires. Amazon kindly refunded my purchase.

Product has 26 month shelf life from date of many. Check the sticker on bottom on product. Mine arrived late July and was produced in March of 2021. Clearly expired. Returning for refund.

Flows in thru valve easy, seals fast and last a good bit!

Quick to seal tires. Trouble free installation

Tutto bene

しっかり目止めされます。今の所、不具合はありません

以前大容量のものを使っていたが、経年劣化が進むようで、必要な性能が確保できなくなり使い切るのが困難であった。少量の製品は単価が高く、大容量なら総額が高いので、そのバランスを考慮してこちらを購入。性能は名前通り一流メーカーである認識を裏切らないもので満足です。

いつも買っていたマックオフのシーラントが売り切れてたのとタイヤをビットリア製だったので本製品を購入。先週ロングライド時に大活躍しました。走行中は気付かず休憩時にシーラントが漏れていたのでパンクに気が付きました。空気圧は5barから0.5barほど抜けていましたがほぼ気にならない程度、穴は問題なく塞がっていたし性能に問題はありませんでした。
