Compatible with Shimano 9150/9100/8050/8000 road rear derailleurs.

They call it a “high-end carbon jockey wheel” (and also “TITAN”) and it’s compatible with Shimano 9150/9100/8050/8000 road rear derailleurs. It features a 13-tooth upper wheel, and 14-tooth lower wheel. But those aren’t any ordinary wheels.

For starters, the guide wheel (top) is made of 3D-printed carbon fiber. They say it’s not only lighter than a metal wheel, it also produces much less chain noise. And because they’re using printed carbon versus molded, they can produce much more complex shapes.

The cage is made with NTPT carbon, which is a brand, standing for North Thin Ply Technology. Essentially, it’s ultra-thin carbon fiber plies pressed together under high pressure to create dense, yet extremely light, blocks of solid carbon. These are then machined into shape, and for the TITAN, it’s one heckuva shape.

The other outstanding feature of the design is the oversized rings supporting the pulley wheels. It’s not just for aesthetics, it offers several performance benefits.

First, they say it allows them to use an oversized bearing, which rolls more smoothly and is stiffer, and with less play so shifting should be more precise. And they use premium SKF Zirconia Ceramic Bearings, with an extremely high P5 precision grade. Not only will those roll very smoothly, but they’re self lubricating, so you won’t need to worry about grease.
