Braking Batfly EPTA Brake Rotor 280mm (Oversize) (BY4135E)
- The outline rotor has increased the performance thanks to the introduction of a new coupling system between rotor and carrier.
- Same BATFLY geometry with directional non round profile.
- Carrier is made of ALUMINUM AL7075-T6 allowing for an optimized shape, reduced weight & higher rigidity, with introduction of a new style.
- Improved rotor to hub load transfer
- The classic rotor-hub coupling system, the pins, are substituted with new connecting components, avoiding deformation and floating variability during product life.
- The new rotor-hub coupling geometry, that allows the rotor stems to slide in radial direction, improves the response to stresses and deformations at high temperature.
- Rotor-hub coupling system is more direct and the two components are in constant and direct contact.
