Chaser 12T Ceramic Rear Derailleur Pulley Wheel with Bolt
Chaser 12T Ceramic Rear Derailleur Pulley Wheel with Bolt
TiWorks Partner Select: supplied through our cooperation with Chaser, this 12T ceramic pulley wheel complements TiWorks titanium drivetrain bolts and small drivetrain upgrade parts.

Rear derailleur pulley compatibility depends on cage design, bolt interface, and pulley position. Please confirm your derailleur model before ordering, especially when using older short-cage road derailleurs.
Our titanium colours are created through carefully controlled surface-finishing processes, including anodising where applicable. These processes enhance the natural character of titanium, giving each finish its distinctive tone and appearance.
Slight variations in colour, brightness and finish may occur due to lighting, screen settings and production batches. Multi-tone finishes may also vary between individual pieces, making each one subtly unique.
