Hutchinsons Blackbird Racing Lab TLR road tyre is a level up from the their Fusion 5 Performance. The art of cycling ultimately boils down to one thing: three square centimetres of contact between your tyres and the road. This small surface has been at the heart of Hutchinson's story since its inception in 1890. Four years of extensive research and development have gone into creating the Blackbird, resulting in the fastest tyre every developed by Hutchinson. Rolling resistance has been improved by 10% compared to the previous generation Fusion 5 but with an increased class leading lifespan of over 4,000 km of real-world riding. Central to the reduction in rolling resistance is Hutchinson's new "SwiftEasy" casing design. This new construction sees the tyres casing wrapped around the bead then bonded directly to a central polyamide puncture protection strip instead of the usual process of overlapping these layers. A final layer of casing runs from bead to bead to reduce air leakage. Swif...
