Review on 🚲 ZSFLZS 2 Pack Bike Tube with Repair Tool Kits: Tire Levers, Patches, Glueless Puncture Rep – A Must-Have for Road and MTB Bike Inner Tube Maintenance by Robert Sisco

1 of 2 Leaks in several places after installation. quality has a problem. I check the outer and inner wheel to make sure my tire is clean before mounting. I only pumped up to 30psi air then saw a flat tire in less than 1 hour without moving anywhere. Found two leaks, the tire appears to be a crack in the flat area, even I received this new tire in less than 1 week. Use the repair tool, scratch area, press the repair pad for a few minutes. Inflate the tire to 20psi and the leak will start again. Remove the tire, throw it in the bin!
