Hi everyone,

I'm a newbie roadie, getting back on my bike this summer. I'm sure a lot have changed since 10 years ago. (Yes, I'm old )

I bought a Continental tube (700x20-25c) as a spare in my emergency kit, and I had to use it a few days ago. For some reason, this tube was WAY way bigger. It practically folded itself as I was tucking my tube inside my tire. I only inflated it to 60psi for the ride back home, since I thought pinching was inevitable...

When I came home, I took out the tube and measured the diameter. It was 39.5 inches (>1000mm)! Is it normal? or did I just get a lemmon?
