Race X Lite Inner Tube 700x18-25 48mm Pack of 5

##Bontrager Race X Lite Inner Tube 700x18-25 48mm Pack of 5 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. Bontrager manage to produce a high quality product that addresses this issue by reducing the wall thickness to 0.6mm yet preserve a reasonable resistance to punctures. This may not sound like much but compared to the normal tube thickness of 0.9mm found in most other tubes this makes a large difference. 48mm valve allows easy inflation with most mid section rims.
