ContinentalTour 700 Presta Tube(Return to Product Page)

An unreliable tube is a royal pain in the rear. My hybrid bike came with CST tubes stock, and they sheared at the valve stem. I had already installed a set of new Continental tires that I was very satisfied with, so I though why not give Continental tubes a try. Right out of the box these showed quality. They were thicker than the CST/Specialized tubes, and the thickness more consistent. The steel valve stem with the locking nut (a rarity for Schraders) was a nice touch. So far, I have put about 600 miles on these tubes without any trouble. No pinholes, no seam tears, no valve stem leaks, etc. They also seem to hold air better, with only minor pumping every week to keep them around 55psi.

You really cannot go wrong with these tubes. The cost is similar to other brands, but the quality is excellent.

I shouldn't be but these tube been lasting so far for me on every curb Jumps.

I have encountered no problems with these tires

Excellent quality from Continental, as usual. I like that the schrader valve stem is steel, not plastic, similar to presta. I was tired of constantly patching/replacing tubes on my daughter's bike - no longer a problem.

I have used these tubes (presta valve version) on three two-week tours, including the Oregon Coast,Pittsburgh to Washington DC via the GAP and C&O Canal, and the Erie Canal, and also a month of touring in New Zealand. Much of these trips have been on hard packed gravel paths. Using Vittoria Cross Pro tires (700cx34), there have been zero flats on any of the trips. The butyl rubber used in the tubes is very flexible and thicker than most tubes. In my opinion well worth any increase in weight and the cost is very reasonable. Any additional weight over other tubes is offset by the fact that I now only carry one spare tube instead of two. I highly recommend these tubes.

The Continental Tour 700 Tube is well constructed and has a nice weight and feel. I've bought some other brands that were very thin and didn't last as long. Fits perfectly in my 700x32 tire and I like that it comes in a Schrader Valve which is what I prefer. Overall, an excellent tube at a reasonable price!

Good tube for a good price, all good

They hold air for quite a while and no issues with any I have used. Good pricing so don't have anything else to say.

I've been using these tubes on and off for years. They hold up well, even when patched.

I bought the tube as a back up replacement for my bike which has a 700x45 tire...I haven't used it yet, hopefully it fits ok...the quality is very good...

Ive always gotten great performance from Conti and these tubes are no exception. I much prefer these steel schraeder valves to the plastic ones.

I love the deals I get here and the great service too. This tube works great for our bikes and is a quality product.

A good tube all around.

I used to get my tubes through Performance bike, but constantly had manufacturing defects. These Tubes just feel more quality and it gives me confidence that when I need to use my spare, it would have a flaw and fail to inflate.

This tube is nicely constructed. The valve stem is beefy for city commuting.

Round tubular shape. Fits inside the tire nicely and holds air as anticipated.

This tube is great value. It is high quality.

Product easy to install.

High quality tube, good valve. Dependable at a great sale price!

I was impressed with the well built tube this is. will get this product again.
