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.
The 25-32 size is really handy because it covers the sizes most commonly used on road and gravel. The 60mm length is perfect for the slightly aero rims I have, no need to mess with extenders and moving valve cores.
The Continental Race Road Tubes do what they're supposed to - hold air. However, I wish that the length of the Presta valves were longer (48mm or so) for better rim clearance.
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!!
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.
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.
I was buying these tires because I wanted a mix of durability and weight savings, and I didn't want to sacrifice ride time for extremely light tubes. Western Bikes Works had the ones I wanted in stock and gave me a great deal on them too. I have not had any flats with them while running them inside some Conti's GP4000's.
I would definitely recommend these to anyone looking for a good training tire that will endure some harsh road conditions in the Spring time when all the roads are about to clear off.
