Review: Quality Continental tubes - These are quality Continental tubes. Continental are my go-to tubes I use for emergencies in all my bikes. They work well, are always uniform in size, and last long a long time in storage. Being uniform, they install easily. I buy these in multiples of 2, because I always seem to go through 2 at a time. The don’t weigh much, and are compact in size, easily fitting in a bike bag. I recently had to fix a flat on my road bike, and had to pull a Continental tubes that had been in a seat bag for at least 5 years. It pumped up easily and got me home.
Review: Very good tire if you keep the pressure high. - Very cool product — very space saving and light — very few flats as long as I keep the pressure over 80 psi. No flats in about 6 mo. 28mm continentals. Otherwise expect snake eye punctures if you hit a bump. Some air loss, so I have to refill every 2 or 3 days. I have had mixed luck with the tire repair patches. I recommend just using a new tire if you get a flat.
