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.
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.
Installed the tube on new tires purchased at the same time. If you need a refresher on how to install tubes, read the instructions on the website before you damage the tube. I have had the tubes in for over 2 months now and have not need to add air. My tire are 700c x 42mm. I have put on about 100 miles, so not very much. Tube is holding up well and I like the metal stem.
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!
I have used a variety of inner tubes over the last 50 years, but the Continental Tour 700 IMO is the best and a decent value as well. In thousands of miles I have yet to see any failure at the stem area (a weak point in any tube) nor have I had any pinch flats. I check the air pressure in both tires before every ride. All tubes leak and these are on the low end. I only need to add air ever other ride.
Just mount them with some talc powder and off you go! No worries.
If you cycle the distance on road touring and carry loads such as panniers this is a must tube! The rubber is a bit thicker and more puncture resistant. They are extremely easy to install. They can handle large pressure without stress. I tour all the time and find the regular 28X32 road tube to thin and they rupture because of the added weight on the rear tire. Therefore, I used to run the tire at a lower pressure. With the Conti Tour tube I can blast the pressure up to extreme levels and no worries about blow out or rupture! Get these if you're serious about touring and want reliability! 5 Stars all the way!
I've had these since I've been running the Continental Top Contact II tires. So far I've been pretty happy with them. I've had two tubes that exhibited a slow leak at the value. This valve appears to have a replaceable core, but if they are threaded loosely into the body, then they will leak, especially if you have to exert much force to unscrew the valve for inflation. A gentle tightening has done the trick for me.
For utilitarian bike riders, or those who will do anything to keep from getting flats, rolling around on balloons is always precarious.
The more rubber, the better - but Thorn-proof tubes are too thick to patch, the tubes with goop inside are tiresome, unpatchable and ultimately leaky, and normal tubes are too thin...in the interest of saving weight? A thin balloon?
...so the Continentals are my current best solution to the dilemma. The rubber is a little thicker.
When something better comes along, I'll get it.
