    This sealer works better than any other
  

*by M***C on Reviewed in the United States on March 10, 2017*

This sealer really works; pre-injected into a good quality tube. I have used it for years in thorn infested southwestern deserts. On rare occasions, If you park the bike right after a puncture and the hole does not have a chance for the sealer to work (it's at the top of the wheel), the tire might lose air, but if this happens you can pump it up, spin the wheel a few times and the sealer will work when it contacts the puncture. Flat Attack does not clot like latex sealers. Lasts for years. A sealed regular weight tube is much lighter than a so-called thorn resistant tube. These heavy thorn resistant tubes are no match for "goat head" thorns anyway, which will work through the toughest tire and tube combo. You are better off using Flat Attack because a hole in inevitable, but if you seal it, it won't lose air.

    Love Flat Attack.
  

*by M***Y on Reviewed in the United States on June 9, 2016*

I've used Flat Attack for years for mountain bikes to baby joggers and kid's bikes. We live in an area that has these blasted thorns that are easily missed unless you're looking closely for them. I've come home from using the jogger more than once to find a tire full of thorns. I then started putting Flat Attack in my jogger tires and so far I can just pull the thorns out, pump up a little and we're good to go.

    Reliable: no flats in 2200+ miles of loaded touring
  

*by M***C on Reviewed in the United States on February 18, 2014*

I am a veteran of tens of thousands of miles of loaded bicycle touring, world-wide. I have tried pretty much all the sealers out there. Flat Attack is by far the best sealer I've found if you are using conventional tires and tubes. It has only one disadvantage: it is viscous and difficult to inject into a tube from the squeeze bottle. For that reason, I started buying these ready made sealed tubes. Unlike latex based sealers used primarily in tubeless tires, Flat Attack does not dry out, so it lasts the life of the tube. The Freedom tubes are good quality butyl rubber. My most recent tour was a across most of the USA, a 2200 mile tour, on an off pavement (rode the Great Allegheny and the C&O towpath N.P. off pavement). My bicycle is a Tom Richey Annapurna (MTB) set up for loaded touring with fairly narrow high pressure tires to fit 26" rims (Panasonic RiBMo - also highly recommended). I had ZERO flats. I topped off the 80psi tire pressure just once or twice; that was it for messing with my tires. These tubes with Flat Attack are the way to go if you hate fixing flats. I ride the same bike at home in "goat head" country (goat heads or puncture vine seeds are notorious for causing flats here in the Southwest). I continue to be flat free, despite a bumper crop of goat heads over the summer.
