LEVEL Ceramic 11-Speed Oversized Jockey Wheel System
In real-world testing conditions, oversized pulley wheel systems have been proven to increase the efficiency of the drivetrain when compared to standard pulley wheel systems. This system optimises the performance of the drivetrain through the use of oversized pulley wheels working in tandem with incredibly low friction ceramic bearings. Compatible with 11-speed Shimano 9100//R8000 rear derailleurs, the LEVEL pulley wheel systems increased efficiency helps to save those crucial watts that could be the difference between victory or smashing those PB's.
- 12T Upper and 16T Lower alloy oversized pulley wheels with ceramic coated bearings for maximum efficiency.
Please note: The oversized jockey wheel system is 11-speed specific and is not compatible with older models of Shimano derailleurs. Nor is it compatible with the 105 R7000 series, derailleurs with a medium cage or those that include an integrated clutch system.
- ONLY compatible with Dura Ace 9100/9150 Di2 & Ultegra R8000/R8050 Di2

- Minimum gear capacity (Upper Gear) 11T
We recommend that you install a new chain at the same time, the oversized pulley wheel system will require slightly extra chain length for the drivetrain to function correctly.
