ContinentalRace Road Tube(Return to Product Page)

It's an inner tube. It holds the air as it should.

Easy to inflate just be sure you have right pump attachment

Nice tubes!

They hold air till they don't

I've never been disappointed with anything I have ordered. Everything comes in as expected and usually quicker than I expect.

Pleasantly very surprised, but after new Pro4 Endurance on the back and Power tires on the front, and using these tubes, I haven't had my usual flat every 2-3 weeks. These have changed my mind about all tubes being the same. Apparently not. Very impressed.

I needed it as a spare tube just in case !

Really this is a great overall tube. Reasonably light and durable. I ride 150 milesweek on medium rough roads. No flats or defects noted.

It worked perfectly. The price was right. And it was delivered in just a couple days. What else is there??

It's a tube, it's not going to change your life. For what it's worth, these are nice tubes, dependable, not prone to flat, the valves have held up and don't leak.

I bought these tubes because I didnt want to risk popping latex tubes during descending. Iv our about 1000 miles on them and they have held up well, no Airloss or punctures.

Heavy duty tube...a little heavier than most, but good when touring in varied conditions.

Switched from other brand due to excessive flats. No problem with Conti so far. Well made and priced accordingly.

A high quality tube. Recommended both for racing and touring.

You can see and feel the quality of these tubes. My previous tubes felt sadly flimsy compared to these.

Have used several of these tubes both on dirty city streets and thorny desert roads with Conti 4000S tires with very few flats. Good air retention, durable stems, and great price. For training and commuting, they are tough to beat.

Very high quality valve and size.

I like everything about these tires.

Shopped around a little and found this to be a great price and delivery was really quick

Consistently dependable tubes.
