One 650x35A stiff bead tyre.
The Wheel Energy laboratory, certified and recognised by the leading global brands, measures several different criteria: grip, cushioning, resistance to wear, longevity, performance.
At B'Twin we design the tyres of tomorrow. Our R&D engineers create prototypes at our international headquarters in Lille, France. These are then tested in our laboratories and approved for use by our professional cycling team to ensure outstanding quality. This expertise is specified on our range of B'Twin tyres with the label "Designed in France".
This is a stiff bead tyre, to avoid damaging it, do not fold it. Store it in its original shape.
For optimal performance of this tyre, we recommend you inflate it to a pressure of between 3.5 and 5.5 bars depending on the type of terrain. You should also check the carcass regularly to avoid any risk of a puncture or an accident.
