Camere d'aria Race/triathlon
Ci sono diverse camera d'aria che si adattano al meglio alle diverse dimensioni dei pneumatici. Le camere per triathlon e corsa su strada hanno in genere valvole Sclaverand; il piccolo diametro della valvola si presta meglio al sottile cerchio di queste biciclette. Le valvole sono lunghe circa 42 mm di lunghezza e pesano tra i 50 ei 90 grammi. Scopri tutti i nostri articoli in catalogo.
Do you have questions about road bike tubes?
Classic butyl tubes weigh about 100 grams or more, while the light versions are already significantly lighter. Latex tubes reduce the weight even further and also improve rolling resistance. For maximum weight savings, however, you will have to reach a little deeper into your wallet for a thermoplastic tube. On top of that, you also get the best puncture protection.
Butyl standard | approx. 105–130 g |
Butyl light | approx. 50–75 g |
Latex | approx. 70–85 g |
Thermoplastic | approx. 35–40 g |
Thermoplastic light | approx. 25 g |

Latex tubes and thermoplastic tubes are good alternatives to butyl tubes, not just because of their low weight. Both materials score points with their more elastic material with better rolling behaviour; TPU is also considered to be more puncture-resistant. The pack size of the latex tube is slightly smaller, the TPU version even significantly smaller. However, the higher price (thermoplastic) or faster pressure loss (latex) makes the butyl road bike tube the first choice for many cyclists.

As the name suggests, butyl tubes with the suffix Light, Extra Light or Ultra Light (depending on the manufacturer) are weight-optimised road bike tubes with thinner walls. This has both advantages and disadvantages:
- + About half as light as normal butyl road bike tubes
- + Lower rolling resistance thanks to less material
- - More susceptible to punctures due to thinner walls
- - More sensitive to assembly mistakes
- - Higher pressure loss than standard butyl tubes
