Tube TUBOLITO S-ROAD 700x18/32MM FV/PV 80mm black DISC 25g

ULTRALIGHT. TOUGH. ULTRA-COMPACT. 

Weighing in at just 25g, this is the world's lightest road inner tube. It's twice as puncture-resistant and significantly lighter than standard tubes (~100g). Made from thermoplastic (TPU) in Austria, it offers superior air retention (comparable to standard tubes, much better than latex) and durability even in sub-zero temperatures. The S-ROAD series is designed exclusively for disc brake wheels (it may not withstand heat from rim brakes). When combined with a lightweight outer tire, you can save over 100g per wheelset compared to tubeless setups. Plus, tire changes and maintenance require significantly less time. Its exceptional compactness makes it the perfect spare tube. Max pressure is 8 BAR/115 PSI (0.5 BAR without an outer tire). Although labelled 18/28mm on the packaging, this tube has been successfully tested with 32mm outer tires.
