ContinentalTour 700 Presta Tube(Return to Product Page)

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.

Very pleased with the product and superb customer service by BikeTiresDirect!

Decided for comfort reasons to upgrade from 23mm tires to 32mm tires. Tried several local bike stores for tubes meant for wider tires with no luck. The biggest advantage to these is that the 23 mm tubes in 32 mm tires leak air much faster. These can go several days without needing to have air added.

Continental products are first rate.

I have encountered no problems with these tires

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!

Just always replace tubes with tires and always happy with thes

What is there to say, they are tubes, bought 4 of these for two bikes I was fixing up to give away, priced right for sure and no problems with them. BTD got my order to me quick as always, which to me is a plus when buying online.

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.

consistent high quality what's not to love!

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

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

Tube seem to hold air for a month now. What more could you ask for?

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.

Good tube. Have had no problems.

Bike roles way fast didn't slide on wet pavment

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