The tire uses a combination of a slightly thicker tread and high density fibre reinforcement technology to offer unrivalled puncture protection and an incredible lifespan that has been tested up to 8000km.All of this comes with hardly any weight penalty, a 25mm tire weighing in at just 255g, even lighter than the competition.A new Hutchinson's Bi-Compound rubber offers a harder compound in the centre of the tire designed to resist cuts and abrasion. This is matched with a softer lateral compound and grooved tread for superior grip when cornering on both wet and dry roads. A 66 TPI casing offers the perfect ratio of weight, protection and rolling resistance.Specifications:- Tire Size: 700X30- ETRTO: 30-622- Concept: Tubetype- Beads: Folding- Reinforcement: Reinforced- Compound: Bi-compound- TPI: 66- Weight (+/- 7%): 320g. tradeinn Bikeinn
