Review on 🚲 Michelin A2 Airstop Road Bike Tire Tube, 25/32 x 622/635, 40mm – Ideal for Front or Rear Wheels by Dustin Berry

These are really cheap tubes. It's punctured quickly in less than 40 miles of use. It may have been bad luck, but when I removed the tire, patched it up, and blew it again to check for a leak, half the tube swelled. This tells me that the material of one half of the tube was much thinner than the other. I was only around 10-15 pounds when he did. Maybe I just got a bad tube, but I won't buy it again just to find out.
