Quieter Sustained Braking

Reduces heat deformation under sustained braking to keep performance quiet and consistent, delivering smoother modulation and predictable lever feel for confident control on long, fast descents and tight corners.

Built to Shed Heat

An updated rotor design combines a more robust arm shape with heat-dissipating paint to improve cooling efficiency. This helps maintain stable braking performance and reduces noise during repeated and sustained braking.
