Ive been running continental tires for years and love them. Just got a new bike that requires valve stem extensions. To use extensions, the core needs to be removed. These tubes have removable valve cores. Now I need to fall in love with these tubes.
Conti's products are fabulous, so of course I was going to get their tubes. I was shopping around and then found that my local Western had the best prices. I bought extras and I haven't had a blowout in a while, but when I do I'll be prepared!!
I started using these tubes before I started using Continental tires (which I use now). I've gone for years without having tube-related flats with these tubes. That experience sold me on Continental. Western Bike Works has always given me the best price and service.
This used to be my go to tube, NOT anymore. The last 3 tubes have all burst at the seams, litterally. All after being ridden for only a few days. Not sure if I got a bad batch but not worth trying these again.
