Formula RO Disc Brakes The RO is the first mass production bicycle brake to use oval caliper pistons. This simple idea created a brake with more power than four piston brakes while maintaining the reliability and weight of a two piston brake. This year we updated the RO to the standard Formula radial master cylinder. This master cylinder makes the RO more compact and lighter than ever before.
