ContinentalTour 700 Presta Tube(Return to Product Page)

Perfect backup for my tubeless gravel bike tires! - small and lightweight but durable enough to hold when there may be some slits or cuts in the casing or sidewall. Carry some tyvek paper to back the holes up if they're too big.

Got theses for my mountain bike to convert it into a rood bike, and theses where perfect.. good quality and good price.

And the customer service is really good, I called them and they were really helpful...

Thank you westernbikeworks ..

Who could ask for more? My order was complete and delivered on time. ContiTubes and Parktool patch kit are staples for all cyclists but when you need them, you need them now.

no issues, size was correct.

These are great tubes, never have issues with them. Solid brand you can trust.

Well made tube! The valve I really like, because my previous purchase from another company the valve threading doesn't even let the cap go fully on before the rubber tubing stops the cap. Compared to the valve your tub has. It goes all the way to the rim and is made out of a rust proof material it seems. Throughly enjoy my purchase.

I bought these as spares for bikepacking. I have always been happy with Continental products.

I called Bikeworks to get a tube for my bike. The tube that I had in my tire was not the right size and was causing a bulge in the tire. The employee was knowledgeable and helpful and knew exactly what size I needed, even though I had no tire size or wheel dimensions. I'll definitley shop here again.

Can't go wrong with Conti tubes, good quality.

I like this tube and the price. It is high quality, thick tubing. I also like the steel nipple. But, the retaining nut is VERY brittle. And, there is no point in using the retaining nut on aero rims.

New to the gravel bike so I have these in for a while to break in the new tires and then maybe go tubeless

these hold air, come at a good price and offer decent puncture resistance.

Good tube for its value.

Tubes have been very durable and easy to work with

Good quality, correct size and easy to install!

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

I've been riding Conti tubes inside the Conti Gator and Grand Prix for years and have been relatively flat free. Yes, we've all picked up the road debris that eviscerates the sidewall and tube, but day in and day out, 100 miles a week, 50 (ish) weeks a year these tubes perform great! Not too heavy, not too thin, easy to mount. Terrific all around performance training tube. I purchase a new set with every set of new tires and pass the still good used tubes off to folks in need.

I read many reviews before deciding on these tubes; it�s been a while since I bought tubes/tires and I didn�t know if I�d need tire liners. The reviews from another rider were what convinced me to try these; I did splurge on the second best tires I found here and one of your phone representatives assured me they would deliver more than enough for my needs. No one wants to be stranded with a flat and these tubes looked like an ounce of prevention to a pound of cure!

This is a great tube with a premium valve stem. The stem is metallic and threaded for the full length. It comes with a valve stem cap as you'd expect but also with a small ring nut. When you install the tube you can then put the ring nut on the stem and spin it down to contact the rim. Typically inflating a tire with no air is challenging because the valve stem is unstable and tends to push down away from the air chuck. With these Continental tubes the valve stem is just as solid and stable with air or without air.

I needed to replace my tire and tube so I purchased this tube. Set up and instillation was very easy and I've had no issues yet with the tube which I've been using for about a month now. For context, I ride about 5-15 miles a week for commuting, and general getting around town purposes.
