With OSPW RS for Shimano Road groupsets, OSPW projects itself into the future with a decidedly modern and angular design. The updated design brings balance and sophistication to the OSPW System, allowing it to integrate seamlessly into contemporary trends in bike and groupset design, which make up the whole of which the OSPW System is a part. With an added level of customization (different logo and pulley options) and innovative new technological features, the OSPW RS meets consumer needs for personal expression and a premium riding experience. The OSPW RS is a statement of where we've been and where we're going - always ahead of the curve. The new design of the OSPW RS isn't just a visual update. The cage itself has been reinforced to offer new levels of strength and durability.
