Formula claims its clever new R.O. brakes offer the power of a four-piston caliper in a stiffer, more compact two-piston package. The secret lies behind the O in the R.O.'s name--a special oval-shaped caliper piston. Formula says these brakes are 15 percent more powerful than their venerable The One model, and they reportedly tip the scales at just 337 grams.
