OSPWRYET RS Ceramic Oversized Derailleur Pulley Wheel (OSPW) 13T-19T Pulley Wheel Fit For Shiman R7000 R8000 R8100 R8150 R9100 R9250
Created: February 06, 2026The reviewer purchased an oversized pulley wheel system for approximately $60, which is a copy of the latest Ceramic Speed design. They note the packaging is nice, and they chose the closed jockey wheel version for aesthetics, better mud clearance, and reduced mud collection. The part is claimed to be 'handbuilt in Denmark,' which the reviewer doubts. The build quality feels surprisingly nice and solid, though the material feels like hardened plastic rather than real carbon fiber. It spins quicker than some original Shimano pulley wheels. The reviewer plans to mount it on a Dura-Ace 12-speed derailleur to test long-term shifting quality and performance, despite compatibility claims that conflict with Shimano's specifications. They also show the pulley wheels have dust covers and bearings that could be replaced with ceramic ones.
