Review on High Performance 700x32-47 Continental Tour Bike Tubes - 4 Pack with 40mm Schrader Valve by Gene Rosado

Recently cycling 3-4 times a week on paved roads again. I bought four packs of these tubes for my aging Gary Fisher hybrid bike because the original front tube held air for rides but went flat after a day. I thought that 10 years with the internal camera is more than good. After installing a new Continental hose and applying proper pressure, the hose remained full even after several days. Only 1-5 pounds are lost by checking the pressure before each ride, which isn't a problem for a tire that can withstand 60-80 pounds of pressure. In any case, the tire pressure should be checked and adjusted before every ride. These whistles have a high quality rating and cost around $9 per whistle which is a reasonable price to me. Satisfied with the performance so far.
