Pirelli Chambre à Air Cinturato SmarTube reinforced 28"

Tiptop. Hält die Luft wirklich gut und lässt sich easy montieren. Rollwiderstand passt und bisher hatte ich keine Panne damit.

Incredible. I never thought I would write such a review. Maybe due to a defective batch, but I have used 4 Pirelli tubes in just two months. Fitted with Pirelli Cinturato Gravel M 35mm, the first two were punctured by a piece of glass. The other two simply did not hold the 4.5 to 5 bar pressure. Basically, once the tube was changed and inflated, after 2 to 3 km it started to lose pressure and remained inflated to about 1 bar. With no possibility of repairing them nor to find out where the leak was. I had bought them with great hope but went back to the traditional butyl ones. I cannot say that I do not recommend against their purchase. Everyone will make their own evaluations. My experience, unfortunately, has been beyond the most negative expectations.
