RevoLoop Tiny Ultra Lightweight 40mm Presta Tube 20" Tyres - 0.9" to 1.5" - 25-406 to 38-406

The REVOLOOP.tiny ultra enhances the performance of all 20 inch tyres. Whether it's a folding bike, a recumbent bike or a bike for the kids: the .tiny ensures maximum driving dynamics and the highest rolling comfort on the road. Not only does it have a low weight of only 21 grams but also the minimised rolling resistance compared to classic products when riding.

The valve made of particularly impact- and break-resistant thermoplastic is ahead of its time. Minimal weight paired with maximum performance. A specially designed valve base prevents damage to the tube caused by sharp edges on the valve bore.

IMPORTANT: Please never fill your REVOLOOP hose with a pressure above 0.5 bar outside the casing. Otherwise there is a risk that the REVOLOOPs will overstretch locally or even burst. Both scenarios mean that the hose is subsequently unusable, as the overstretching of the hose does not deform again and the hose can therefore no longer be fitted. Therefore: REVOLOOP hoses should only be pressurized to over 0.5 bar when fully assembled.
