Tubes 700X28-35 Sv 36Mm27X1-1/4

Installed them over a year ago but still have to add air to one tire, now and then. Better than having to insert the substance yourself into the valve, though. There are lots of sticky balls around here.

I'm done with flat prevention tubes like these and the Slime products. Sometimes they seal, sometimes they don't. Sometimes they seal the valve and you can't add air. Plus they're heavy (weight always matters on bikes) and expensive. The puncture resistant TIRES, like Schwalbe with their puncture number rating, and Kenda "Plus" tires with Kevlar cord work so much better.

seems to work fine holds the air ....i thought it was flat fixer or special kind of patches did not know it was a inner tube with stuff in it

probably a good product, but had to return it twice for the exact same reason, so I requested a refund on the last return.... the wrong size tube was in the box, it was delivered both times with a 26inch tube inside the box, instead of a 29inch as marked on the box.

Pros: eco friendly, family owned and operated company, its made of thick durable material, high quality tube, 5 year warranty and easy to install.Cons: None.i love this tube! i love a company that works towards becoming eco friendly and treats their customers with ease. I tried going to walmart and they didn't have the tire i needed (even though they sold me the bike there) so i had to buy off of amazon. I highly recommend this product to anybody, rather it be a novice bicyclist or a pro on a budget!

I must've missed something here because the tube commenced leaking straight off. Green goo starting coming out of the valve within an hour of being installed in my tire and it was done by my LBS. I went back and had them change the tube, never even rode with the Flat Attack. I was very disappointed because it seemed like such a great idea.

the tubes were bought as a gift for my dad who rides everyday. there wasnt a problem with the product. they fit without problems, he is very satisfied and so am I..

I purchased two of these tubes and had one go flat almost immediately. There was a slow leak near the valve stem where the tube was joined together. I purchased another one to replace the bad one and it leaked in the exact same place. There is a quality control issue with the tubes.
