The new SWR HSL cranks are made of the latest generation of carbon fibre with a "hollow structure" system and a four-arm design. The innovative "High Stiffness Link" gear mounting system with six attachment points allows for greater rigidity and shifting precision, thanks to the additional attachment points' positioning, located in critical torsion areas on the gears. The gears are made of AL7075-T6, finished in CNC for quick, precise shifting: the surface treatment of anodizing with the TT (Total Treatment) process guarantees optimum resistance to wear.
