The new OSPW system features Ceramic Speed ​​FURTHER DRIVE technology – which consists of two new technological features that aim to increase the drivetrain's ability to function efficiently over time. Active Debris Remover (ADR) feature - a new and unique dust cover design that is securely anchored in a recess of the pulley wheel, thus completely enclosing the bearing. This feature is combined with a grooved structure that surrounds the dust cover and which dynamically pulls debris away from the pulley wheel as it rotates. The ADR is paired with new 14 and 20 tooth solid disc pulleys, simply known as ALPHA. The ALPHA album has a two-piece structure. A separate narrow and wide tooth profile manufactured from a composite material offering long-lasting wear protection and noise reduction. Additionally, a solid aluminum disc eliminates the possibility of foreign objects getting caught between the pulley spokes, adding strength and rigidity to the pulley design. FURTHER DRIVE technology is combined with a completely new cage structure that uses stronger materials, without adding unnecessary bulk, and which is perfectly in line with the robustness that the Eagle Transmission group is famous for. But the real value lies in the ability of FURTHER DRIVE technology to provide peak performance during races or the season, when runners need it most.
