This review is from: Dr Sludge Inner Presta Valve Self Sealing Tube (Sports)
My Bicycle had been getting a few flats a week from thorns etc, so I decided to give these a try.Sure enough in the first 7 days I fitted these tubes I noticed that my front Tyre had lost about half it's pressure ,though not completely flat .I Pumped the try back up and it's stayed up ever since .
Great! Self sealing inner tubes :-)
