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.
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!!
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 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.
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 put these on and haven't had a single flat....yet !! Seriously they were easy to put on and they have held up very well. They loose very little air.I haven't had to put air in the tubes in months.And most importantly to me like I said, I haven't had one flat since I put them on!!
