Gold STC represents the ORRO gold standard in ride quality with a competitive frameset weight and clean aesthetic. The geometry of our longest running model has been revised across a myriad of generations to create a bike which seamlessly balances speed with efficiency for endurance riding. The rider is perfectly positioned to allow for full focus on the ride ahead while the Sigmatex engineered spread tow carbon frame offers ride dampening qualities for unrivalled comfort. Our unique relationship with Sigmatex, who are a UK based carbon composite specialist, allows us to have an intrinsically detailed and supportive design ethic so we can produce the best results. The STC material was chosen for its combination of low weight and high stiffness allowing us to optimise certain areas of the frame for the ride characteristics that we wish to promote. This has given us a future classic in the Gold STC - a bike of climbing category weight with all the comfort and efficiency required to take on any endurance challenge you can point it at.
