Continental 26" Freeride Bike Inner Tube - 2.3"/2.7" Width, 42mm Presta Valve - Durable Bicycle Tire Tube for Mountain Biking & Off-Road Adventures

I never thought a tube would make such a difference in the riding experience of a bicycle but these tubes are superb. The moment I started to ride after installing them I immediately noticed a huge difference in the way the bike felt on the road... it felt much more responsive and the feedback I felt from how the ground felt beneath the tires was superb. I was absolutely floored by the difference between what I had to what I have now...i used to just purchase a cheap off the shelf tube that fit... never again. I can't say just yet how they'll perform over time but the immediate difference was so obvious I can't ignore it and will be replacing the tubes in my other bike immediately even though it doesn't need it. It gave my bike a completely different and a much upgraded riding experience... I'm a very satisfied customer for now.
