Lightweight tubes are commonly used by competitive riders and racers. Lightweight tubes (700x18-23 size) typically weigh around 70g, a standard weight tube usually weighs just over 100g. Lightweight tubes create a faster rolling wheel and livelier road feel, but are not as durable as standard weight tubes.
Made of butyl rubber, lightweight tubes can be patched using a standard patch kit. Because the rubber is so thin, the patch may create an imperfection felt while riding.
