🚴 High-Performance Panaracer 2 Pack 700 x 18 / 25 C Presta (French)-80mm Bicycle Tube: Superior Quality for a Smooth Ride Review

don't worry about getting flat, it's "pre-flat". The first tube I inserted had a hole and no pressure. I must have paid for one tube, not two.

Best value for money. Because of where I live, I go through several tubes every summer. Even walking without cameras sometimes can't stop the giant goats in my area. These pipes are easy to install, lightweight and economical.

Between my racing bike, my husband's racing bike and our tandem we had nothing but an apartment - 11 apartments in 4 months. I can hear air escaping from the valve on my rear wheel as I write this. Just today I put 2 and 2 together and found - those must be bad lamps! Don't skimp on your lamps and buy something better.

Amazing! I live in San Francisco, so there's a smorgasbord of broken glass, trash and syringes on the streets - and it's inaccessible to all of them! Sometimes I notice big holes or cuts on the tire's outer rubber from driving over said objects, but the chamber remains unopened! the hard inner shell really does. I am so happy with it and 3 months of sound tires.

I drive over 1000 miles a month and have tried many tubes and found this to be the best value. I buy the 80mm version for my Zipp wheels and it's nice to have that option at this price point. They are medium weight which is what I want. You can save about 25 grams by buying lightweight tubes, but remember that flat tubes are much easier to come by, with little to no increase in performance.

I wanted these. They are thin and mostly uniform when inflated. I had an issue installing a commuter bus on my Trek Madone for commuting. The original tube expands too much, causing the tire to rub against the frame at one point. These solved the problem. After a day of commuting, a pipe developed a leak, luckily 1/4 mile from home. I found a leak along the seam on the opposite side of the valve where the two pieces of tubing connect. The rubber material doesn't stretch as much as the tubing…
