With the Air+ tube, you need to inflate your tyres only every six months (maintaining a pressure between 3.9 and 2 bars). Thanks to a proprietary material containing silica and titanium - a Michelin exclusive - the Air+ is three times more airtight than an Airstop Butyl tube of the same size. Safe and sound Engineered for urban use, touring and leisure riding, the Air+ uses a 1.2mm wall thickness (versus 0.9mm for standard tubes), making it particularly resistant to punctures. Its distinctive gray color also gives it a unique appearance. |
