Câmara de Ar Válvula Schrader

The seams come apart. Seems like Specialized sold out quality for profit

I put these on, liked the ride for about five 20 mile rides, then my bike was in the rack with a flat. The a seam came apart. Seems to be an issue with specialized tubes lately.

I’ll give this two stars because the front tire has made it a month and is going strong. It sucks when you use your Mt bike for hunting and don’t even make it to your spot before your pushing your bike because not only one small thorn puncture. But two in the same tire. Not sure what to think. They also do not hold a patch well at all.

Seems much heavier than my normal tubes. No flats yet!

Specialized Thorn Resistent Tubes are one of my most recent purchases. Got these tubes for peace of mind on a ride over all kinds of terrain and debris on roads and trails; even if a flat occurs, oh well, call AAA Road Service!

Werth the investment of not having too worry about being an expensive tube and it deffinatly has lasted me a year....im on the first set of tubes i bought from specialized and these puppies definatly stop punctures...

So far so good, these tubes with slime in them work very well on the trails I ride on.

I havent put them on yet but they appear to be much thicker than my regular tubes. I suspect they will do the job

They're great product for a good price...

Very thick tire rubber materials. So far in the Arizona High Desert where thorns are numerous, no flat tires as of 2 months.

Great tubes, I live in Phoenix and it’s basically thorn testing grounds.

I was sent a link to these by a friend who ordered them for his bike years ago. They are fantastic! First thing I did was ride around an area that I knew had thorns on the ground. I pulled them out one by one and NO FLATS!

So far it has prevented flat tires. Before using these, we had 2 flat tires in 1 day. There are some nasty thorns on the trail we ride.

Superb protection from goathead thorns at a sound price.

These tubes add considerable weight to your bike but prior to installing I had six flats in twelve rides from thorns . So even though I haven’t had a flat with them there is a trade off . Overall I think I think it’s worth it .

Excellant

Great for kids or casual riding. Very thick and tough but very heavy. Can actually feel gyroscopic force when turning when you have speed

I installed these with my new tires and so far they have worked well.

Wow! Sooo much thicker than tube I replaced. Very much impressed. I’m going to order another one for my front tire.

Much thicker than ordinary tubes. I am a very big guy. I pop ordinary tubes just by sitting on the bike. At least 300 miles on them so far, no flats.

I ride alot on the ditch banks. A normal tube didnt last one ride. The specialized thorn proof tube has made about 30 rides. No problems
