Deva Ceramic Pulley Wheels
Deva Ceramic Pulley Wheels are the pulley set used in the Brandtal oversized derailleur cage system. Built for riders chasing real drivetrain efficiency: less drag, smoother chain motion, cleaner power transfer.
This is a precision upgrade, not a fashion part. Tight tolerances, premium ceramic bearings, and an oversized design that reduces chain articulation stress compared to standard jockey wheels.
What you get
- Lower drivetrain friction through the pulley system
- Smoother pedal feel, especially under load and at high cadence
- More stable chain tracking in the Brandtal cage
- Premium finish suited to high-end road builds
Why ceramic and oversized matters
Ceramic bearings reduce rolling resistance versus standard steel bearings. Oversized pulleys reduce chain bend angle as the chain passes through the derailleur, which helps efficiency and can improve drivetrain smoothness.
Does it make you “instantly faster”? It is a marginal gain. But it is a real gain, and you feel it in the drivetrain when everything is clean and correctly set up.
Compatibility
Designed for the Brandtal oversized derailleur cage system. Not intended for standard derailleur cages.
FAQs
No. These are designed specifically for the Brandtal oversized derailleur cage system.
You are buying a marginal efficiency gain. Reduced friction can improve power transfer, especially over long efforts, but it is not a “night and day” change.
A smoother drivetrain feel and cleaner chain motion, particularly under load. Best results come from a clean chain and correct derailleur setup.
No special rituals. Keep the drivetrain clean, avoid blasting bearings with high-pressure water, and inspect periodically like any high-end component.
