4 Piston, 2 pairs of axially mounted pistons Initial braking force uses 14mm pistons, for superior control Higher hand loads additionally release the 22mm pistons giving maximum braking force when you need it!
Advantages:
Braking action gives excellent modulation for light hand loads Max brake conditions total piston area is equivalent to 26mm pistons!. External fluid transfer improves heat dissipation of brake fluid preventing ˇ§pump-upˇ¨ Air cooled pistons Unrivaled aesthetics
