Review on Slime Cycling 30057: Self-Sealing Inner Tube Puncture Sealant for 🚴 Schrader Valves, Prevent and Repair Bike Tire Leaks, 700x35/43c - Black by Robert Blanton

Slime has always worked well except for this bike tube. After frustrating trial and error trying to inflate the tube, I took it off the rim, removed and replaced the valve (clogged with gunk) but still not inflated. Removed the valve and found hardened mucus on the lower part of the valve stem. After cleaning and installing a new valve, the hose will inflate. Inflate/deflate the tube first before installing it in the tire so you don't get frustrated. I haven't rated durability yet. First see how it works in summer,
