OSPW RS 3D Titanium for Shimano 9250/8150

The OSPW RS 3D Titanium is designed to blend seamlessly with the modern, angular design trends of 2026's elite frames. By utilizing additive manufacturing (3D printing), CeramicSpeed has created hollow titanium pulley wheels that are 10% lighter than their aluminum counterparts while offering double the service life. This system reduces drivetrain friction by 35–40% compared to a stock Shimano setup. It features a 13-tooth upper and 19-tooth lower pulley combination and comes standard with Coated Ceramic Bearings for near-zero friction and a lifetime warranty.

Key Features

• 3D-Printed Hollow Titanium: State-of-the-art pulleys that are incredibly light, structurally superior, and highly resistant to wear.
