The fastest bicycle tyre ever tested features the lightest tubeless-ready casing on the market. This race-day specific weapon has raised the bar on tire technology! The Corsa Speed uses a proprietary Graphene G+ ISOtech compound, which is then paired with an ultra-fine Corespun-T casing. The end result is a tire that maintains the lowest rolling resistance, while still providing the trademark Corsa suppleness, and outstanding wet weather grip. When used in tubeless form, the casing works perfectly with sealant, providing an even higher level of flat protection.
