The Supertype HSL cranks are made of carbon fibre using a “hollow structure” system, with a four-arm design.
“High Stiffness Link” gear mounting system with six attachment points allows for greater rigidity and thus greater shifting precision: the additional attachment points’ position are located in critical torsion areas on the gears.
Chainrings are made of 7075-T6 AL, finished with CNC machining, with a special design to improve up and down gear changes, therefore ensuring precise shifting. The chainrings are finished with a special anodizing surface treatment called HT (Hard Treatment) this process ensures the chainrings are hardwearing.
