Meanwhile the underexposed collection represents the reserved below the radar Peter with blacks greys & rainbows. Its time to start chasing your own rainbows. Theyre not afraid to say that the gripton compound is the best out there. & when combined with an ultra-supple 320 tpi cotton casing you get a tire thats very special, you get the turbo cotton tire. But dont take our word for it, its Peter Sagans tire of choice & because of his love for it theyve made him a Sagan limited edition version. Both materials stand for master craftsmanship & they work in harmony to reflect the dedication to building the worlds fastest tires. By bringing both of these materials together theyve created the best clincher tire out there. It provides a clear-cut performance advantage.
