##Bontrager Race X Lite Inner Tube 700 x 18/25 48mm Over the years it has been alleged that a single gram saved on something that turns is equal to three grams on a static component, so weight saving in something as mundane as the humble inner tube is nothing to be sniffed at. In their Race X Lite Inner Tube 700 x 18/25 48mm, Bontrager manage to produce a high-quality product that addresses this issue by reducing the wall Bontrager to 0.6mm yet preserve a reasonable resistance to puncture. 48mm valve allows easy inflation with most mid section rims.
