Varying tube types can affect your tyres' handling characteristics: the Standard tube, available in all dimensions is the best choice for everyday cycling whilst Light & Supersonic varieties give racers the option of lower rotating weight, therefore increasing speed. The lightweight tubes have a lower thickness and it is imperative that inflation pressures are maintained to prevent the risk of pinch flats. For worry-free cycling, we recommend the Hermetic Plus tube. Its improved formula is lighter and more compact, which renders it very puncture resistant due to the the presence of higher butyl amounts and greater wall thickness. Since it retains air longer, it's a favourite among bicycle rental agencies. Our Freeride and Downhill tubes are especially strong and bulky, which make them our favourites, since their extra wall thickness effectively protects against punctures.
