From the top range model Eureka SHM50, used by Team CCC Sprandi in the Giro d’Italia 2015, Guerciotti presents anotherversion of Eureka. So, it is born Eureka SX50. Unlike the model SHM50, it has been used the standard brakeset system, not usingthe Integrated Brakeset System, while it has been used the solution of Integrated Fork System, as used now in all the top rangemodels of Guerciotti collection. In the production of Eureka SX50 has been used the same design of model SHM50 in orderto give continuity both at level of frameset and tech features. In fact, also the model SX50 has the same performance features:comfort, good controllability and stability. The material used in the Eureka SX50 are similar to those ones used in the SHM50:75% 24Tons Intermediate Modulus UTS50 Carbon Pre-Preg + 20% 30Tons High Modulus with High Strength IMS60 CarbonPre-Preg + 5% High Impact/High fatigue Strength K3 Clothed Carbon Pre-Preg. The application of high performance compositematerials technology and special graphite fiber/epoxy are the same material system apply on the structures of aeronautic andaerospace. The using of these materials and technologies permit an excellent power transfer and low fatigue, achieving andmaximizing the riding durability and stability.
