fragile, not for gravel
I bought 2 pair of these to use on my gravel bike. I have had several punctures with them. One of these appears not be puncture in any place when submerged in water, however the tyre keeps getting deflated within 12 hours. Not worth the money or even the weight saving, not a useful alternative to usual inner tubes if gravel riding is what you are after

As advertised

Montate su gravel, rispetto ai 49 grammi indicati la mia bilancia ne segna 55 direi che ci siamo, un po’ care, io le uso anche sulla corsa ma ovviamente in altra misura. Tra le camere in butile da 150/160 grammi circa a queste per le due ruote si scende di 200gr giusti, oltre a migliorare il rotolamento. Sono a mio avviso un po’ più rumorose delle camere tradizionali, forse perché meno elastiche producono un rumore diverso. Queste della Pirelli le monto per la prima volta, le altre camere in TPU vanno controllate perché un po’ di pressione la perdono.

Good Gravel TPU inner tube with a long, durable valve. I believe it has less risk of the valve core coming loose compared to the Schwalbe Allround.

Sono leggerissime come previsto, 100 grammi meno delle camere d'aria nere. Eppure al tatto sono solide. Al primo giro si sente una discreta differenza con meno inerzia sulla ruota e leggermente migliore scorrevolezza.

Abbastanza voluminosa anche se pesa metà di una classica camera d aria
