StopFlats V2 20" X 1.5-2.0" Yellow Bicycle Tire Liner-Single

Wife got a new bike. First time riding and goat head (thorn) caused a tube leak. Put these in and no more leaking tubes. Used them years ago for the kids bikes and never been unhappy with them. Best part is when you get the bike out, the tires still have air. Can't tell you how many family bike rides were cancelled due to flat tires. Well not any more!

I swear by these as they have provided many years of flat free riding. As for the naysayers that claim they cause friction flats, that may be true with other liners but the Stop Flat liners are a soft & very pliable type of material that seems to mold itself very well to the inside of your tire. If I have to replace a tube every 5 years from a friction flat I would still consider these liners a great investment for the protection they provide.
